machine will not boot after moving root
by Michael Hennebry 26 Apr '21

26 Apr '21

I'm trying to move my root directory from sda5 to sda3. After running grub2-install and grub2-mkconfig, my machine will not boot. I performed the changes using a F33 live DVD which also fails to boot. After plugging in a USB-connected SD card with Centos 7 on it, the F33 live DVD decided to boot. It is what I am running now. The complaint is UUID 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a not found. While running F33 live DVD I get blkid | grep 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a /dev/loop1: LABEL="Anaconda" UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" BLOCK_SIZE="4096" TYPE="ext4" /dev/mapper/live-rw: LABEL="Anaconda" UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" BLOCK_SIZE="4096" TYPE="ext4" /dev/mapper/live-base: LABEL="Anaconda" UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" BLOCK_SIZE="4096" TYPE="ext4" I backed up sda5 with rsync -auHAXUUx . I copied from the backup with the same flags. I edited the new etc/fstab to point at sda3, actually LABEL=local3slash .

NOKEY warning from yum update

26 Apr '21

On F33, yum update gives me ...

Also from google: rpmfusion-nonfree-appstream-data - Appstream metadata for the RPM Fusion nonfree repository The message seems to be aganst the repository rather than an individual package. Huh? Why would an update reach out to a previously unused repository? For that matter I'm not all that sure it did. I'm pretty sure I've used rpmfusion nonfreee before. Why would it be balking now? What do I do about it? This problem predates the root change mentioned in another thread (... won't boot after moving ...). I'd suspected, clearly incorrectly, that it had something to do with the fullness of my root partition. Until I have a solution, is there a way to tell yum to update everything that does not involve rpmfusion non-free? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

Announcements for manual configuration intervention?
by Matti Pulkkinen 23 Apr '21

23 Apr '21

Hello! TL;DR is there a list where announcements are made regarding configuration changes requiring manual intervention? Today I noticed that the clock in my Fedora 33 workstation install was about five minutes fast. Some examination revealed that none of the sources chrony was using for NTP were working. There was, however, a new configuration file, /etc/chrony.conf.rpmnew, which changed the sources from specific IP addresses to a pool URL. It would have been nice if there was some kind of notification that the current chrony configuration is broken, and it can't be fixed automatically. Is there a list, or some other method, by which I could be notified of these sorts of things? Not for specific packages necessarily, but just in general, even if it is high-traffic? -- Terveisin / Regards, Matti Pulkkinen

dangling symlinks and upgrades (was "invisible application after upgrade").
by home user 22 Apr '21

22 Apr '21

(context) In the "invisible application after upgrade" thread, Ed did not know how I did my upgrade to f33. I responded that I mostly followed the Fedora upgrade instructions from here: "https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/", and listed the sequence of commands that I did. That included the steps symlinks -r /usr | grep dangling symlinks -r -d /usr from the "Clean-Up Old Symlinks" section. Andras responded that > This isn't necessarily a good idea, because those dangling symlinks > may belong to their respective packages. If so, removing them will > compromise the integrity of the package they belong to. If Andras is correct, then the upgrade instructions need to be changed. Based on past experience, when a bug is submitted against Fedora documentation, the Fedora documentation team will want suggestions on how the document should be worded. (question 1) What should the instructions say? Is there a better yet easy and safe way to find and clean out dangling symlinks? Maybe more detail should accompany "After you verify the list of broken symlinks"? (question 2) In a later post, Andras provided and example of a dangling symlink (in the "hunspell" package) that should not be deleted. When I was a C/C++ programmer (a long long time ago, in a galaxy far far away), dangling pointers (and memory leaks) were naughty; they can cause serious problems. Isn't a dangling symlink a file system parallel to a dangling pointer in a C/C++ program? What good, valid purpose is there for a package to have a dangling symlink? Or maybe "hunspell" needs a little clean-up?

Automount occasionally failing to auto-unmount
by Patrick O'Callaghan 22 Apr '21

22 Apr '21

I use automount with systemd service units (not /etc/fstab) to mount an external BTRFS filesystem (2 drives configured as RAID-1). There is a timeout of 120 seconds of inactivity after which it should unmount. This works *nearly* all the time, but sometimes it doesn't and I can't figure out why. The drive is normally only used at 3am to run a backup script, and logs show that this is working correctly, but when I check in the morning I sometimes find the drive still mounted (shown by 'findmnt') even though nothing is accessing it, i.e. 'fuser' shows nothing and 'umount' succeeds immediately. If it matters, the actual timeout always seems to take 300 seconds. I don't know if this is because BTRFS is keeping the drive alive, flushing queues or whatever. It's not important in itself, just another data point. When I mount the drive manually, the timeout always succeeds (though again after 300 seconds rather than 120). Any ideas? poc

Does anyone know of a way to get ncat to listen on port 53 when using systemd-resolved? [root@meimei ~]# ncat -l -4 -p 53 Ncat: bind to 0.0.0.0:53: Address already in use. QUITTING. (no rants, please) -- Remind me to ignore comments which aren't germane to the thread.

Canon MF642Cdw works as expected on F32 but fails on F33
by dwoody5654＠gmail.com 16 Apr '21

16 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

aegisub no more working after update...
by François Patte 16 Apr '21

16 Apr '21

Bonjour, I just update my system (fc-32) and aegisub is no more working: I can open subtitlefiles but not the corresponding video... Here the message: (aegisub:347417): Gdk-ERROR **: 12:08:25.195: The program 'aegisub' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 37349 error_code 2 request_code 150 (GLX) minor_code 24) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) I don't understand what it means and don't know what to do.... Thank you for any help. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte FSF https://www.fsf.org/blogs/community/presenting-shoetool-happy-holidays-from…

Third level choosers for keyboard keys.
by AV 16 Apr '21

16 Apr '21

This question is just because I am curious, I don't need the functionality. Is there a way to enable "third and fourth level choosers" in F33/34 Workstation (Gnome) to enable typing a third symbol on keyboard key? F33 gnome-tweaks has an option for a compose key and it works under both Wayland and Xorg. I use it regularly. But I can't find an option for third level. F34 workstation has an extra option to 'Type Special Characters' in gnome-settings with the 2 entries: one for 'Alternate Character Keys' and one for 'Compose Key'. Neither of these seems active (at least with Wayland). But the gnome-tweaks 'compose key' setting still works in F34. (after further investigation I will bugzilla this). And I can't find out what this 'alternate character' option is supposed to do. KDE plasma has settings options for compose and third level but neither of these works under Wayland (not implemented yet). Have not tried Xorg yet. There should be a possibility to edit some config file somewhere but I have not been able to find it. Or is it (still) not enabled under Wayland in any case. AV

Networksolutions is indeed your registrar. It's an extra charge for them to provide your DNS servers. If you are paying for that service you aren't using it as you have things pointing elsewhere: Name Server: NS3.ATTDNS.COM Name Server: WS.LINUXLIGHTHOUSE.COM
