Today I tried upgrading again from Kubuntu 22.04 to 24.04. I found Muon
was gone. A bit of research and I found that muon isn't included in
24.04. Next I tried opening Synaptic to enable all the third party
repositories that were disabled during the upgrade. I was surprised to
see that Synaptic didn't show the repositories. The window opened but
there was nothing where the repositories should be. I found a solution
for that, so I'll pass it along in case this is useful to anyone. In a
Thanks for sharing your experience. I also upgraded to Kubuntu 24.04 about 2 months ago and discovered I could not print to my network printer (Canon D570).
The print job would remain stuck in the queue. Poking around in the /etc/cups/printer.conf.
It appears cups-browsed overwrites the network printer "DeviceURI" ipp://Canon-D570.local:631/ipp/print"
with "implicitclass://Canon_D570/" To fix this I have to reconfigure the printer every time I reboot my desktop.
