[nmglug] upgrade packages with apt

[Brian O'Keefe]

Hello all!

I haven't seen any messages from the group so I don't know if it still 
exists. I miss Ted's summaries and input. So I feel bad that my first 
communication in a very long time is me carping about a problem and I 
hope you folks can have tolerance for me!

ASUS laptop running Ubuntu 20.04 with Mate desktop

I ran a normal upgrade as indicated by the package manager, which is at 
least every couple of days if not daily. I ran the upgrade and all 
seemed fine. However, an error symbol popped up in the panel and it 
noted there was an apt error and to run "apt --fix-broken install". I've 
done this many times in the past and the dependencies or conflicts are 
fixed. However, not this time. Here's the output of that command:

$ sudo apt --fix-broken install

No matter what I try I cannot run an upgrade nor even a simple "apt 
autoremove"

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
  libpipewire-0.3-modules : Depends: libroc0.3 (>= 0.3.0+dfsg-3~) but it 
is not installed
  libtiff5 : Breaks: libtiff5:i386 (!= 4.4.0-4ubuntu3.3+20.04.sav1) but 
4.4.0-4ubuntu3.3+20.04.sav0 is installed
  libtiff5:i386 : Breaks: libtiff5 (!= 4.4.0-4ubuntu3.3+20.04.sav0) but

I try this this:

It seems like a circular problem of the libtiff5 packages breaking each 
other. I've considered removing one or the other but the additional 
packages to be removed scares me as so many packages depend on them.
