puzzling SELinux alert.
by home user 13 May '21

13 May '21

At least 3 times in the past few days I've seen the same SELinux alert. I put the text of the details in the attached file "alerts.txt". All 3 occurrences were while using caja to rename or delete a file, though it does not happen every time I rename or delete a file in caja. These alerts confuse me. There is no directory "/memdf:"... -bash.1[~]: cd / -bash.2[/]: ls -a . boot etc lib64 mnt root srv system-upgrade usr .. .cache home lost+found opt run sys system-upgrade-root var bin dev lib media proc sbin sysroot tmp -bash.3[/]: ls -a /memfd* ls: cannot access '/memfd*': No such file or directory -bash.4[/]: Also, the directory name (ending with a colon?) looks fishy. Further, the filename ".nvidia_drv.XXXXXX" looks fishy (but "legal"). The instruction does not work: -bash.4[/]: /sbin/restorecon -v /memfd:/.nvidia_drv.XXXXXX (deleted) -bash: syntax error near unexpected token `(' -bash.4[/]: -bash.5[/]: /sbin/restorecon -v /memfd:/.nvidia_drv.XXXXXX /sbin/restorecon: SELinux: Could not get canonical path for /memfd:/.nvidia_drv.XXXXXX restorecon: No such file or directory. -bash.6[/]: I gather that a directory and or file (whatever its name really is) are missing? How do I fix this?

Strange compress behavior under /usr
by Qiyu Yan 13 May '21

13 May '21

Dear folks, My problem is that new file created at /usr won't be compressed. I accenticly that none of my files under /usr is compressed[1], so I tried to run `sudo btrfs fi def -czstd -v -r /usr` to compress them, that seems to work. And `sudo compsize /usr` now gives Processed 431312 files, 224528 regular extents (230971 refs), 253758 inline. Type Perc Disk Usage Uncompressed Referenced TOTAL 56% 7.2G 12G 13G none 100% 3.5G 3.5G 3.5G zstd 39% 3.6G 9.2G 9.7G This seems pretty good, but when I am testing dding to dump a file to /usr to test compress for new file, problem happens: [root@yan-desktop /]# dd if=/dev/zero of=/usr/1 bs=10240 count=10000 记录了10000+0 的读入记录了10000+0 的写出 102400000字节（102 MB，98 MiB）已复制，0.0426441 s，2.4 GB/s [root@yan-desktop /]# dd if=/dev/zero of=/etc/1 bs=10240 count=10000 记录了10000+0 的读入记录了10000+0 的写出 102400000字节（102 MB，98 MiB）已复制，0.0585055 s，1.8 GB/s [root@yan-desktop /]# compsize /usr/1 Processed 1 file, 1 regular extents (1 refs), 0 inline. Type Perc Disk Usage Uncompressed Referenced TOTAL 100% 97M 97M 97M none 100% 97M 97M 97M [root@yan-desktop /]# compsize /etc/1 Processed 1 file, 782 regular extents (782 refs), 0 inline. Type Perc Disk Usage Uncompressed Referenced TOTAL 3% 3.0M 97M 97M zstd 3% 3.0M 97M 97M Just ignore those Chinese output by dd, it doesn't important... But as you can see: file created at /usr/1 is not compressed at all while file created at /etc/1 gets compressed. There should not be any difficult to compress all-zero contents for zstd. There should not be so much difference between /usr and /etc, they are in same subvolume named "root" mounted at /. [root@yan-desktop /]# btrfs su li / ID 256 gen 1530662 top level 5 path home ID 257 gen 1530662 top level 5 path root ID 266 gen 1530614 top level 257 path var/lib/machines ID 292 gen 1530585 top level 257 path var/lib/mock ...[some container storage subvolumes] and mount options for / is rw,noatime,seclabel,compress=zstd:3,ssd,space_cache=v2,subvolid=257,sub vol=/root (subvol=root,noatime,compress=zstd in fstab) lsattr /|grep -E "var|etc" gives -------------------- /etc -------------------- /var `btrfs property get /usr` or `btrfs property get /etc` gives empty output. How do I troubleshoot this problem? [1] That is also a problem since I setup compress after upgrading to fedora 34, and have done many package updates since then. So new extents written to /usr should be compressed while compsize reports none of them. -- Qiyu Yan GPG keyid: 0x4FC914F065F2DF12 About: https://fedoraproject.org/wiki/User:Yanqiyu

Evince sendto (share) button greyed out
by Anca, Tibor 12 May '21

12 May '21

Hello, since the switch to Fedora 40 I notice this odd change, that neither nautilus context menu (Sendto entry missing), nor evince share/ sendto button work. The latter doesn't work at all which makes things unnecessary complicated. I understand that the package nautilus-sendto has been integrated into nautilus-extensions, which now provides a libnautilus-sendto.so. But this hass no observable effect on Evince. Is this a bug that I should look for/ file, or <irony> a feature that I cannot appreciate in its full beauty </irony>? Besides: Fedora 34 is a great work and Gnome 40 works otherwise flawlessly on my Thinkpad E485! Kind regards Tibor -- Dr. Tibor Attila Anca Pastor Ev.-luth.

System Failure?
by home user 11 May '21

11 May '21

I did my weekly patches (dnf upgrade), rebooted, and logged in as a regular user. A problem popped-up. The top part of the details is below. I'm not (yet) seeing any other problems. Is this a false alarm? If not, what should I do? --------------- not-reportable The backtrace does not contain enough meaningful function frames to be reported. It is annoying but it does not necessarily signalize a problem with your computer.

KDE Desktop Scaling in Xorg
by Stephen Morris 11 May '21

11 May '21

Hi, I am running F34 in a Vmware player VM, and issue with KDE not starting in F33 seems to have been rectified F34, however KDE with Xorg will not scale. I have a file in /etc/X11/xorg.conf.d that supplies an xorg modeline to set the screen resolution to as close to 4K as the vmware player will allow. If I start the vm in the default window size when Gnome starts Xorg starts in 800x600 resolution, then when I maximise the window Gnome scales to the "4K" physical monitor resolution because of the existence of the modeline, which it also did in F33. However when I do the same thing with KDE it remains at 800x600 resolution, whereas in F33 before the issue that stopped KDE from running surfaced, maximising the window scaled the desktop resolution. Does anyone know why this is modeline statement is not working for KDE in F34 any more? regards, Steve

Gnome 4 in F34 Dash location
by Stephen Morris 11 May '21

11 May '21

Hi, I am running Gnome 4 in F34 after doing a system upgrade from F33. This environment is running in Vmware Player. The Gnome Dash is displaying at the bottom of the screen which I hate with a passion, how do I move it back to the left side of the screen like I had it in F33, I can't find any option in settings or Tweakui to do this? regards, Steve

nagios and dnf
by Łukasz Posadowski 11 May '21

11 May '21

Hi. Can You recommend a plugin, or a shell/prel/python wrapper for dnf checks in Nagios? Is there a widely accepted one? I'm finding only plugins for older yum versions, which, according to readmes, may not work with dnf. I would really like if it would use cache and do not "dnf update" every time. I wrote my own wrapper, but it rely on a local cron jobs and temp files, which I don't like. thanks -- Łukasz Posadowski

Restored f33 on new drive from a tarball now a problem
by Robert McBroom 11 May '21

11 May '21

New drive has the same msdos partition structure as the old. Legacy system with boot partition on a separate drive and from the root partition. System boots in mode 3 as specified but entering id and password flashes some text and returns to the login. Edited the grub entry to try a graphical boot but still get textmode. What can be done to get access to f33?

file associations for OVF files
by Paolo Galtieri 10 May '21

10 May '21

I recently ran into an issue with files with .ovf extension. The issue is that VMware Workstation will not import files that end in .ovf. A file that ends in .ovf shows up as follows of Fedora 34: file *.ovf returns XML 1.0 document, ASCII text What's interesting is that if you have VirtualBox installed and then try to open a .ovf file with VMware workstation it works because according to the VirtualBox documentation: Oracle VM VirtualBox creates file type associations automatically for any OVF and OVA files on your host OS. In fact if I run caja and click my way to the OVF file, right click on the file and look at the properties I get: Type: Open Virtualization Format (application/x-virtualbox-ovf) If I don't have VirtualBox installed I get Type: XML document (application/xml) So who should setup the file association for .ovf files? How do I go about changing the association for .ovf files from XML document to something else so that I can associate it with VMware Workstation? Any help is appreciated. I have reported this issue to VMware also. Thanks, Paolo

F34: wrong default audio output device
by Sam Varshavchik 10 May '21

10 May '21

After F34 upgrade the default audio output device is wrong after every reboot. After every reboot it is, apparently, a "PCM2902 Audio Codec Analog Stereo", which goes anywhere. It's not much of hassle to go into Volume Control and click on "Built-in Audio Analog Stereo", but it's rather annoying. Does anyone know where and how to set the default?
