Intel's Clear Linux optimizations
by František Zatloukal 06 Aug '25

06 Aug '25

Hi, Phoronix recently release article[1] about Intel's Clear Linux with some cool graphs showing nice performance gain compared to Xubuntu. I didn't have time to dig in and look how it's performing against Fedora, but I'd assume Fedora can be compared to Xubuntu in terms of compiler settings. I think i'll be interesting to look into it and find out if Fedora can't tweak compiler settings (eg use LTO for critical things like Mesa, Kernel, ...). I think it could be interesting fo Fedora users to have this enabled if there are not any disadvantages other than compile time, compile memory usage and so on. What do you think?

dnf "no match for group package" on upgrade...
by Matthew Miller 02 Jun '25

02 Jun '25

I'm seeing a number of people confused by this message, usually followed by some actual transaction error. I _think_ this is happening because these packages are in comps but do not exist in the distro. Is this correct? I tried to search for it, but the error message is _very_ common in ... well, people who are asking about it because of what I said. (For example: https://unix.stackexchange.com/q/542877/2511) I found https://bugzilla.redhat.com/show_bug.cgi?id=1538346 but not much of a general resolution. It does note that one issue is arch-specific packages (which maybe just need "arch=..." in comps?). I think we should: 1. Have a schedule standarded task to remove any packages listed but non-existent after branch from rawhide. (I assume a Rel-Eng task?) 2. Have DNF make this message less scary. Maybe even move down to a debug message and not show it by default — I am not seeing a situation where they're useful to _most_ end-users. Anything I'm missing? -- Matthew Miller <mattdm(a)fedoraproject.org> Fedora Project Leader

Orphaned magic-wormhole + its python deps
by Fabio Valentini 21 Jan '25

21 Jan '25

Hi everyone, I have just orphaned magic-wormhole (the original one written in Python) and its dependencies. I no longer use it, I have no time to fix the packages for new Python versions, and upstream is pretty much dead since they started porting the project to Rust. - python-magic-wormhole - python-magic-wormhole-mailbox-server - python-magic-wormhole-transit-relay - python-txtorcon - python-spake2 - python-hkdf There is an alternative Go implementation of the "Wormhole Protocol" (wormhole-william), for which eclipseo already submitted a review request. It seems to be better maintained than the Python original, if we want to have a Wormhole client in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1922806 The official port of magic-wormhole to Rust also seems to be progressing, we might want to package that one instead once it's released: https://github.com/magic-wormhole/magic-wormhole.rs Fabio

Applications with AppData and not visible in the software center
by Richard Hughes 14 Oct '24

14 Oct '24

We've been looking at the AppStream extractor issues in Fedora, and we've come across a few broken applications. Broken apps are not visible in the application installer. The apps include: * albumart * apitrace-gui * appstream * asylum * audience * bomber * bovo * calligra-braindump * cervisia * choqok * classified-ads * crrcsim * cube * curblaster * dsi * escape * ettercap * font-manager * freedink-engine * gap-core * gnofract4d * gvrng * hgview * hyperrogue * kaddressbook * key-mon * kgraphviewer * knotes * konqueror * LabPlot * nextcloud-client (maybe fixed in distgit) * openms * openvibe * owncloud-client * pingus * pioneer * portecle * qdigidoc * qjackctl * qsynth * qtikz * recoll * renku * rodent * screengrab * screenruler * simple-ccsm * slashem * spectacle * speed-dreams * tennix * tilp2 * tortoisehg * trophy * tzclock * uzbl-defaults * vdrift * vegastrike * wireshark-gtk * xfce4-power-manager * xfpanel-switch * xskat * yakuake * zanshin * zathura The full list, along with what failed is available here: https://dl.fedoraproject.org/pub/alt/screenshots/f26/failed.html If you want any suggestions or advice, I'm happy to help. Most of the failures are pretty self explanatory, e.g. "No <summary> in AppData" or "icon was too small 24x24" -- our guidelines are here: https://github.com/hughsie/appstream-glib/blob/master/README.md#guidelines-… As a reminder, you can validate AppData files using: appstream-util validate-relax file.appdata.xml Thanks, and comments welcome. I can set up a script that sends email to the package maintainer if this would be helpful, but I thought we might be able to get the majority of these sorted with this email. Richard.

sysusers scriptlets: what to do if upstream includes the config files?
by Adam Williamson 26 Jul '24

26 Jul '24

The guidelines for sysusers packaging: https://docs.fedoraproject.org/en-US/packaging-guidelines/UsersAndGroups/#_… say: "Create a <package-name>.sysusers file with the user definition and add it to the specfile as a source...use the %sysusers_create_compat macro to consume it in the %pre section: %pre %sysusers_create_compat %{SOURCE3} " but...what are you supposed to do if *upstream* ships the config files? openQA recently added these to its upstream distribution, so it seems wrong to replace the config files upstream ships with ones separately packaged downstream. But if I don't package them as source files, how can I set up the %pre macro? I tried this: %pre %sysusers_create_compat usr/lib/sysusers.d/geekotest.conf where usr/lib/sysusers.d/geekotest.conf is the path to one of the sysusers config file within the upstream source, but it doesn't seem to work. The built package has no %pre script. However, that does work if I eval it locally from an openQA source tree: [adamw@xps13k openQA (master %)]$ rpm --eval "%sysusers_create_compat usr/lib/sysusers.d/geekotest.conf" # generated from geekotest.conf getent group 'geekotest' >/dev/null || groupadd -r 'geekotest' ...etc... so...help? Is there any way to make this work right? Thanks! -- Adam Williamson Fedora QA IRC: adamw | Twitter: adamw_ha https://www.happyassassin.net

F35 Change: Debuginfod By Default (Self-Contained Change proposal)
by Ben Cotton 05 Jun '24

05 Jun '24

https://fedoraproject.org/wiki/Changes/DebuginfodByDefault == Summary == Fedora users / developers who need to debug/trace distro binaries can make use of the recently activated elfutils-debuginfod servers to automatically fetch debugging data and source code, instead of having to use `# sudo dnf` commands. == Owner == * Name: [[User:fche| Frank Ch. Eigler]] * Email: fche(a)redhat.com == Detailed Description == Numerous fedora debugging-type tools have built-in capabilities to use the [https://sourceware.org/elfutils/Debuginfod.html debuginfod] protocol to fetch debuginfo/source code automatically. We would like to activate a setting so that Fedora's debuginfod servers are automatically used, rather than requiring hand-editing individual users' dot files. == Feedback == There has existed [https://www.spinics.net/lists/fedora-devel/msg279002.html broad interest] in a Fedora debuginfod server since the project was proposed / announced in 2020, and several distros already operate public servers of this nature. Some of the distros configure their installations by default to talk to those servers, some do not. Turning on this by default has some limited privacy implications. Some Debian users have [https://lists.debian.org/debian-devel/2021/02/msg00262.html expressed concerns] that this facility "calls home" during debugging, so it may expose a limited amount of information about what a user is debugging. The information is limited to the build-id and source code file names of programs being debugged, and is only sent to the servers if their machine lacks locally installed debuginfo. Whether this should be opt-in or opt-out and how has been resolved there via an install-time query to the sysadmin. In contrast, on OpenSUSE Tumbleweed, it is [https://build.opensuse.org/request/show/879926 simply defaulted-on], and we have heard of no controversy. We anticipate discussing this topic on the mailing list, and noting it in the release notes either way. == Benefit to Fedora == This will improve developers' experience. It may reduce download server burden, as only individual ELF/DWARF/source files are downloaded rather than entire `-debuginfo` and `-debugsource` RPMs. It would help Fedora catch up to other distros who put up `debuginfod` servers already. :-) == Scope == * Proposal owners: The work could consist one extra parameter in the `elfutils.spec` `%configure`. Its effect is to arrange for the `elfutils-debuginfod-client` RPM to install an `/etc/profile.d` file that sets the `DEBUGINFOD_URLS` environment variable automatically to `https://debuginfod.fedoraproject.org/`. (At the time of this writing, the _staging_ server is getting ready for testing: `https://debuginfod.stg.fedoraproject.org/`.) * Other developers: None - relevant code has been previously upstreamed! * Release engineering: None - our team is operating the `debuginfod[.stg].fedoraproject.org` VMs. * Policies and guidelines: N/A (not needed for this Change) * Trademark approval: N/A (not needed for this Change) * Alignment with Objectives: N/A == Upgrade/compatibility impact == None. Note that these servers index all active Fedora releases (32-), all architectures, so users of those versions can already set `DEBUGINFOD_URLS` manually to take advantage. == How To Test == * Install `elfutils-debuginfod-client` * Open arbitrary fedora binary via gdb. ** Admire the immediate downloading of debuginfo and source code. * Run `eu-stack -v -p $pid` for an arbitrary process. ** Admire the immediate downloading of debuginfo to give precise file:line data. == User Experience == Primarily: users running debuggers, profilers, tracing tools on internet-capable machines can work immediately, without switching to privileged users and fragile manual `dnf` commands to install this data. == Dependencies == The `debuginfod` servers at `fedora-infra` need to be up. == Contingency Plan == * Contingency mechanism: change the elfutils-debuginfod-client subrpm to not set the default `DEBUGINFOD_URLS` environment variable for all users. In the case of a server outage, the debugger tools revert to debuginfo-less operation, prior to this feature. * Contingency deadline: shortly before freeze * Blocks release? No == Documentation == There is upstream documentation in the debugging tools as well as associated with the client code / cli tooling. What our Release Notes would focus on however is the _automatic activation_ of this facility via the environment variable. == Release Notes == TBD. -- Ben Cotton He / Him / His Senior Program Manager, Fedora & CentOS Stream Red Hat TZ=America/Indiana/Indianapolis

future of dual booting Windows and Fedora, redux
by Chris Murphy 29 May '24

29 May '24

Summary: Windows 10/11 increasingly enables Bitlocker (full disk encryption) out of the box with the encryption key sealed in the TPM. Two different issues result: 1. Fedora's installer, Anaconda, can't resize Bitlocker volumes. We could use better documentation to help the user perform the volume resize in Windows, before proceeding to booting our installation media. The documentation probably should be explicitly referenced by the Windows version of Fedora Media Writer. 2. The Bitlocker encryption key is unsealed only if the boot chain measurement by the TPM matches the expected values in a TPM PCR. When shim+GRUB are in the boot chain, as is the case in our default dual boot installation, the measurements are wrong, and this means the GRUB menu entry to boot Windows won't work. The user is dropped to a Windows Bitlocker recovery page. If they have their backup encryption key handy, it will work but to say the least this condition is unexpected and not user friendly - not least of which is many users won't have this backup key handy since they didn't take the action to enable Bitlocker in the first place. The bug report for this is https://bugzilla.redhat.com/show_bug.cgi?id=2049849 It was a Fedora 36 final release blocking bug, but considered a "difficult to fix" exceptional case, moving it to Fedora 37 final. Some of the options for consideration: a. Fix GRUB by giving it the ability to modify UEFI NRAM "bootnext" value, so that instead of chainloading the Windows bootloader from GRUB, GRUB will modify the system NVRAM such that the next boot (only) will directly boot the Windows bootloader. Thus far there's no interest by GRUB upstream. Whereas systemd-boot has implemented it. b. Add a user space utility modifies system NVRAM such that the next boot (only) will directly boot the Windows bootloader. And also remove the Windows boot entry in GRUB, on UEFI systems. (It would be retained on BIOS systems.) c. Change the release criterion. https://fedoraproject.org/wiki/Fedora_36_Final_Release_Criteria#Windows_dua… Current: The installer must be able to install into free space alongside an existing clean Windows installation and install a bootloader which can boot into both Windows and Fedora. Replacement: The installer must be able to install into free space alongside an existing clean Windows installation, install and configure a bootloader that will boot Fedora. d. Consider the problem sufficiently difficult to fix that we need an extension to the exceptional case allowance, and wave the bug for another release. Thoughts? -- Chris Murphy

some man pages have bugs, can't be grep'd
by Chris Murphy 27 Mar '24

27 Mar '24

I've been seeing this since clean installing Fedora 30. I don't recall ever seeing it before, including on a Fedora 29 -> Fedora 30 upgraded system (is now the clean installed system). [chris@flap ~]$ man rpm | grep -C 10 rpmverbosity <standard input>:176: warning [p 3, 0.8i]: cannot adjust line [chris@flap mantest]$ man rpm >rpm.stdout 2>rpm.stderr [chris@flap mantest]$ ll -rw-rw-r--. 1 chris chris 62 Jul 16 14:24 rpm.stderr -rw-rw-r--. 1 chris chris 28498 Jul 16 14:24 rpm.stdout Is this a bug that should be reported against rpm or something else? I'm certain I've seen it in other man pages, but offhand I can't find another example. -- Chris Murphy

Unretire ulogd (or another NFLOG logger?)
by Chris Adams 21 Feb '24

21 Feb '24

I'd like to use NFLOG to log firewall drops (so that the kernel message log isn't spammed by them), but it doesn't appear there's anything currently in Fedora that can read that other than "tcpdump -i nflog". It looks like ulogd was retired a while back because it only had a SysV init script and nobody stepped up to convert it to systemd (which should be really simple, since the old init script is pretty much a textbook template of a SysV init script). Am I missing anything? Is that all it needs? Is there another NFLOG logger daemon? -- Chris Adams <linux(a)cmadams.net>

Co-maintainers for my ham packages
by Matt Domsch 23 Nov '23

23 Nov '23

Due to an impending move to NYC and related downsizing of my house into a 2-bedroom apartment, I'm selling all my ham radio gear. Therefore I won't be able to test any of the Fedora packages I maintain with actual hardware. Would anyone be interested in maintaining or co-maintaining these? - direwolf - Sound Card-based AX.25 TNC - CubicSDR - Cross-Platform Software-Defined Radio Panadapter - liquid-dsp - Digital Signal Processing Library for Software-Defined Radios - sdrpp - SDRPlusPlus bloat-free SDR receiver software - SoapySDR - A Vendor Neutral and Platform Independent SDR Support Library - soapy-rtlsdr - SoapySDR module for RTL-SDR hardware Thanks, Matt N5MLD
