I hope one or more of you can help me.
I upgraded today from Ubuntu 18.04 LTS to 20.04 LTS on my desktop
computer. (I know I am way behind, but I can do this only in the summer
etc., etc.)
I used the built-in Ubuntu update feature.
It worked better than I expected and took less that two hours. The data
backups I did ahead of time took much longer.
Anyway, 20.04 is running but I have two problems.
Number One:
Many terminal commands give this message:
Errors were encountered while processing:
linux-image-4.15.0-212-generic
Processing was halted because there were too many errors.
W: Can not find PkgVer for 'linux-image-extra-4.4.0-122-generic'
E: Sub-process /usr/bin/dpkg returned an error code (1)
In particular, here is what happens when I try to remove 4.4.0-212.
sudo apt-get --purge remove linux-image-extra-4.4.0-212-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package linux-image-extra-4.4.0-212-generic
E: Couldn't find any package by glob
'linux-image-extra-4.4.0-212-generic'
E: Couldn't find any package by regex
'linux-image-extra-4.4.0-212-generic'
Number Two:
I cannot get audio out of Line Out to my speakers. And I cannot get
audio into Line In to make recordings. I *do* get audio from the audio
output on my HDMI monitor. This might be related to the need for codecs,
but when I try various terminal commands to load more codecs, I get
problem Number 1 !
Some of what I read on the Web mentions tex files that could cause
Number 1. I do have TeXstudio installed. I tried to uninstall texstudio
and texlive, but when I do that, I get the message ant Number One!
I'd appreciate any help or suggestions.
Thank you.
