Cannot install Update Manager!!! [SOLVED]

See post #19 above, first one!

The single file "10_q4os.list" triggers the error, weird. Let this single .list enabled and others disabled for now and post output of:
$ qrepolist
$ cat /etc/apt/sources.list
$ cat /etc/apt/sources.list.d/10_q4os.list

In post 19, the results of the two 'sudo apt update' commands show lines beginning with "N:", at the end of which it seems that apt is searching for packages suitable for the 'mfcj5720dwlpr' and 'mfcj5720dwcupswrapper' architectures.
Could be interesting to see the outputs of
$ dpkg --print-architecture
$ dpkg --print-foreign-architectures

Yes, excellent idea, post the output please

First, the requested contents of the lists.d directory:

$ ls -al /etc/apt/sources.list.d/
total 44

-rw-r--r-- 1 root root  143 Feb  4 10:37 q4p-debian-backports-20250204103739-pEe.list

(I had restored all the list names after doing the one-by-one trials.)

Next, @hchiper's suggested commands output:

$ dpkg --print-architecture
amd64
$ dpkg --print-foreign-architectures
mfcj5720dwcupswrapper
mfcj5720dwlpr

Anything else?

q4osteam · 2025-06-08 18:14

Well, now we see at least one problem on Apt data, thanks to @hchiper. Such foreign architectures are ultimately bad, they had to be added to your system in some wrong way. Now, they are muddying Apt update attempts.

Run to remove bad archs:
$ sudo dpkg --remove-architecture mfcj5720dwcupswrapper
$ sudo dpkg --remove-architecture mfcj5720dwlpr

$ dpkg --print-foreign-architectures
the output must be clean.

Then run:
$ sudo apt update
and post the output again.

@hchiper
Great suggestion

Durhammer · 2025-06-08 18:42

Done! Thanks to both of you, @14osteam and @hchiper!

2 packages can be upgraded. Run 'apt list --upgradable' to see them.

Now to see if I still can print and scan....

q4osteam · 2025-06-08 18:47

That looks fine, however we see 2 packages waiting for upgrade. They could be held back still by some alien non-Debian packages, so run:
$ sudo apt -V full-upgrade
and see if it's processed well.

Once you run apt update, it should show that all packages are up to date. At that point we can consider your Apt system to be consistent and really clean.

Durhammer · 2025-06-08 19:00

All packages now up to date.

I have been able to verify that the printer still works, but I cannot find a scanner app in the menu. Software Centre SAYS Skanlite is installed, but it doesn't show up!

EDIT: nevermind! I was able to launch it from the command line. It works, but it's waaay too limited (can't crop, etc.). I need to find and install the one I use on MX, it's nice.
