Canon MF642Cdw works as expected on F32 but fails on F33
by D&R 15 Apr '21

15 Apr '21

I was able to print and scan from Fedora 32 but when I upgraded to Fedora 33, cups shows "waiting for printer to become available". I am using the driver from Canon: linux-UFRII-drv-v520-usen-05.tar.gz. The install.sh that is included looks for the following packages: libjpeg-turbo beecrypt beecrypt-devel libglade2 jbigkit-libs libgcrypt libgcrypt-devel which are installed and current, and all the above packages have had a point increase. The install.sh also states that Fedora is supported. Looking at the jobs page first message is "Rendering is complete", then "Waiting for printer to become available". I called Canon and was told that the driver was not 100% Canon code and that it was unknown when a updated driver would be available. The current driver was released in 09/2020. Any ideas on how to fix or work around, Thanks, David

NetworkManager IPv6 Router Advertisement tracking
by Adam Chasen 15 Apr '21

15 Apr '21

How and where does NetworkManager track prefixes from Router Announcements? I recently changed my router advertisement to remove a prefix which previously had a 24 hour expiration on it. I thought I would be able to manually remove the removed prefix before expiration from the appropriate connections via `ip` commands, but the address and route come back with every router advertisement I receive on that interface (even though the RA no longer includes the prefix). The address entry show the "count down" of `valid_lft` appropriately: 2: eno1 inet6 xxxx:6081:1a02:1102:b534:7b79:6baa:d27c/64 scope global deprecated tentative dynamic noprefixroute valid_lft 43371sec preferred_lft 0sec I can watch the address from the removed prefix get added via `ip monitor` when a RA comes in (seen with `radvdump`). The router advertisement does not contain the prefix (seen with `radvdump`). NetworkManager manages this connection, but I cannot figure out where/what is tracking the stale (but not expired yet) prefix. I find no references to the prefix in `nmcli connection` outputs (except the "capitalized" runtime keys) and didn't see anything in /var/lib/NetworkManager/ or /run/NetworkManager/. Thanks, Adam

I think I broke my BTRFS RAID 1 array
by Richard Shaw 14 Apr '21

14 Apr '21

I have been running a 3 disk RAID 1 btrfs array for a few weeks now and simulated more than a dozen power failures without issue. Yesterday I decided to add my 4th disk, which was the original media drive. I was able to add it to the array easy enough and then initiated a full balance, however, when I was trying to squeeze the case panels back on (SATA power cables are stiff!) two of the drives (sdc, sdd) lost power. I didn't notice the problem for a few minutes until I looked at the storage section of Cockpit. I immediately initiated a shutdown and corrected the issue by rerouting the power cables a bit. After booting back up I tried to restart the balance but it would run briefly and then stop. dmesg shows: [ 155.497940] BTRFS info (device sdc): balance: start -d -m -s [ 155.499804] BTRFS info (device sdc): relocating block group 10451967541248 flags data|raid1 [ 162.517172] BTRFS info (device sdc): found 15 extents, stage: move data extents [ 162.776081] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [ 162.776087] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [ 162.776090] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [ 162.855784] BTRFS info (device sdc): balance: ended with status: -117 I ran a scrub and a little over 5 hours later it shows it made 4 corrections: # btrfs scrub start -B /mnt/media scrub done for d9a2a011-77a2-43be-acd1-c9093d32125b Scrub started: Tue Apr 13 17:09:51 2021 Status: finished Duration: 5:20:52 Total to scrub: 7.34TiB Rate: 399.47MiB/s Error summary: verify=4 Corrected: 4 Uncorrectable: 0 Unverified: 0 WARNING: errors detected during scrubbing, corrected However, when I try to balance again I still get errors: [19480.281381] BTRFS info (device sdc): balance: start -d -m -s [19480.298196] BTRFS info (device sdc): relocating block group 10451967541248 flags data|raid1 [19485.587630] BTRFS info (device sdc): found 15 extents, stage: move data extents [19485.801278] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [19485.801287] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [19485.801288] BTRFS error (device sdc): tree level mismatch detected, bytenr=10359313989632 level expected=0 has=2 [19485.865739] BTRFS info (device sdc): balance: ended with status: -117 Where do I go from here?

How to kickstart a workstation installation?
by Thomas Cameron 14 Apr '21

14 Apr '21

Right now, if I want a workstation, I use the bootable workstation image on a USB thumb drive and choose to install the workstation image to my hard drive. Then I have to go back afterwards and run a bunch of yum groupinstall commands to get my machine where I want it. Not ideal for multiple installations. I used the F33 Everything DVD image and got closer, but I still don't see a way to use it to kickstart a VM or a desktop. I even used the Fedora Server DVD image and did a bunch of yum groupinstall in %post, but every time I got an error about plymouth and it hung. How the heck do I kickstart a workstation? Preferably from the F33-Everything DVD image so I can set up Xfce. Thomas

F33 -> F34 upgrade resulted in unbootable system
by Jeb Wilkins 14 Apr '21

14 Apr '21

I thought I'd test the F34 upgrade to look for bugs but its resulted in an non-booting laptop. I've a fairly stock Fedora install on a Dell XPS 13 developer edition. The latop was originally an ubuntu install, its got LVM on top of LUKS created by ubuntu, Fedora partitions were later added inside of LVM. Separate dedicated fedora boot partition outside of LUKS/LVM. Nothing much has been changed on the machine at a system level, its primarily for web development so all changes are in $HOME. I've just upgraded from F33 to F34, upgrade seemed to go fine but on reboot its hanging after decrypting LUKS but during mount of root and swap. I've tried various restarts. I've checked the filesystems from a live disk, those are fine. Seems LUKS decrypts, initrd boots but mounting root fails - no error, just hangs for hours at a time till I give up. [ OK ] Reached target: Local encrypted volumes [ <=> ] A start job is running for /dev/mapper/..... (Xmin Ys / no limit) I've a parallel ubuntu install I can use to test stuff out if anyone has any suggestions? Thanks in advance

systemd-resolved, split dns, & vpn setup
by Jack Craig 13 Apr '21

13 Apr '21

hi list, I have a small home domain (linuxlighthouse.com) running on fedora 32. I am trying to set up network services for DNS & HTTPS I have only the one server that I'm trying to provide all these services from, a single host using a static ip from att. i have a cascaded router config connecting my external ip, 108.220.213.121 to it's internal 10.0.0.101. I have tried at length to get bind 9 to support proper a split horizon configuration without success. I came across two very informative articles about systemD-resolveD and their future implementation on F33 as standard routing/resolution for DNS. the second article added focus on systemD-resolveD split DNS and VPN configuration. This was looking like a good solution until I got down to the end of the second article where it said, if I understand this correctly, the systemD-resolveD is not appropriate for the primary DNS server of a domain. that in fact you need dns domain server to use bind instead. so I am confused about how to jam all these related services on a single host?? My question to this group is, at this point in time, where is the best place for me to post queries on this set up? a future goal is to use wireguard vpn once the above issues are resolved. suggestions? should queries be sent to this mailing list or is there a more appropriate list? thank you in advance for your consideration, Thx, jackc...

I thought that because I was a Domain owner, I had to do the translation from my public IP to my local DNS name You can do, but you don’t MUST do it. I to have a split horizon, but updating records at my dns-provider is a rather masochistic exercise. Besides, it changed hands four times. in as much as networksolutions.com<http://networksolutions.com>, my domain registrar provider, has already the IP and host name then I don't need to provide that so let me trim off that external. zone I'm assuming that I still need to provide service for the 10.0.0.0 internal addresses, but that could just be covered by my /etc/hosts file right? Only if you serve it to a single machine in your lan, /etc/host is a sensible option. If you have multiple machines in your network, bind remain the ultimate solution (imho). Besides, hosts is only useful for translating names to numbers and vice-versa. Anything else: (txt, srv, etc) not possible. So: “viva bind!” With this new bit of information, I should be able to run a minimal configuration as you earlier outlined I was trying to throw in everything plus the kitchen sink. I'll start ripping the plumbing out of named.conf; see how little I can get away with. Once again thanks for your time!!

It'll usually be done where you register your domain name. Though you can shift it elsewhere. You can renew a domain name and host it with a different company. You can have a company host your website, and they can also host your DNS records. For what it's worth, if they do your mail and website through something like cpanel, they'll probably want to host your DNS records, too, so their cpanel software can control any changes the DNS records. You can run your own slave name server, that follows what the public one does. This can be handy, but not essential, to keep an eye out for anything that goes wrong. If you want to run dynamic DNS, so you can log into your home computer from somewhere else on the net without having to know your IP, that's a different thing, again. But, if you want to be your DNS server for the whole world, they have to be able to connect to you. Traffic has to be able to get through. And you will need a fixed IP. _______________________________________________ users mailing list -- users(a)lists.fedoraproject.org<mailto:users@lists.fedoraproject.org> To unsubscribe send an email to users-leave(a)lists.fedoraproject.org<mailto:users-leave@lists.fedoraproject.org> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure Dit bericht kan informatie bevatten die niet voor u is bestemd.

invisible application after upgrade.
by home user 13 Apr '21

13 Apr '21

(f33; gnome) I just finished upgrading from f32 to f33. When I click the gnome "Activities", I no longer see "caja". When I use the gnome activities search thing, it does not find "caja". But dnf shows it installed and up-to-date. Before today's update, caja was easily available through the gnome Activities. How do I get caja back into the gnome Activities, and visible to the gnome Activities search? Thank-you in advance. Bill.

Newbie Info - Linux and Intel
by David 12 Apr '21

12 Apr '21

If one goes to the Intel website and does a search on "Linux," they will find several articles, that may be of interest to someone interested in Linux drivers for Intel components. For example. https://www.intel.com/content/www/us/en/support/articles/000025890/ethernet… While their pages do not mention Fedora, there are some that mention RHEL, which should apply. Feel free to elaborate, if you have insight into all that. Any drivers that claim they are compatible with Ubuntu are likely compiled for Debian Package Manager. So they will not work in Fedora. I do not know if there are generic drivers that work in both .rpm and .deb. Can someone please elaborate on all that ? Is Intel support for Linux excellent ? or amazing ? I would say that their support for Fedora is lame, compared to their support of Clear Linux. And, that their support of Red Hat or Fedora is not as good as their support for Ubuntu. Intel's community forum does allow specific questions about Fedora. For example: https://www.intel.com/content/www/us/en/search.html If that link does not work, try a general search there, such as "Fedora 32." There are hundreds of post there from Fedora users asking for troubleshooting help, going back several years. David Locklear

Trouble with firewalld
by Jonathan Ryshpan 12 Apr '21

12 Apr '21

Looking through the system logs (journalctl --boot), I stumbled on the following error messages from firewalld; it looks like the function iptables-restore is called fairly frequently, generally after the system wakes up from sleep, and never succeeds. The intervening lines vary. Is this something to worry about? Apr 09 07:16:49 amito firewalld[926]: ERROR: '/usr/sbin/iptables- restore -w -n' failed: iptables-restore: line 9 failed Apr 09 07:16:46 amito systemd[1]: Started Hostname Service.
