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

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

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.

So there is nothing I know of to correct this. Can anyone help?

Thank you all
