Canon MF642Cdw works as expected on F32 but fails on F33
by dwoody5654＠gmail.com
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,

aegisub no more working after update...
by François Patte
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.

Third level choosers for keyboard keys.
by AV
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.

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

NetworkManager IPv6 Router Advertisement tracking
by Adam Chasen
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,

I think I broke my BTRFS RAID 1 array
by Richard Shaw
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

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

However, when I try to balance again I still get errors:

Where do I go from here? Googling "tree level mismatch detected" shows
mostly source code results.

How to kickstart a workstation installation?
by Thomas Cameron
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.

F33 -> F34 upgrade resulted in unbootable system
by Jeb Wilkins
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
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...
