No way to update python3.10 on my linux mint mate 20.3 Una

Question

Last night the update manager indicates there are 2 update ready. I want to apply them but at the end only one updates the 2nd one (python 3.10) does not. It was late so went to bed. This morning that update is still there but now there is some more stuff.

Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://apt.postgresql.org/pub/repos/apt focal-pgdg InRelease' doesn't support architecture 'i386'

It was not exactly the same as mine related to codelite. I looked in repositories and ppa´s and found an entry for codelite and disabled it. That message was gone. But the update still did not work. This time a problem with the mirror I was using. Changed mirror and all the rest runs fine. Still updating python 3.10 no way. Other updates do pass, even python 3.8 and 3.9. Clearly the problem lies with python 3.10 and seem dependency related but I am stumped.

The deadsnakes repository is there. I removed and reinstalled it. Still same problem.

Here is a screen shoot of my terminal (same messages appear when I use synaptic):

It all turn around two dependencies that python 3.10 needs but are no longer there. But the recommended commands do nothing but return the same result.

The following packages have unmet dependencies. python3.10 : Depends: libpython3.10-stdlib (= 3.10.4-1+focal2) but 3.10.4-1+focal1 is installed python3.10-minimal : Depends: libpython3.10-minimal (= 3.10.4-1+focal2) but 3.10.4-1+focal1 is installed

So what is going wrong? what apart from focal1 and focal2 is different? And are they fundamentally different? Most importantly how do I solve this problem without going in circles.

Oh and before I forget. My python console in gedit stopped working at the same time as these problems started and I can't make out what the problem there is either. Suspect though they are related. e

Thank you in advance.

Answer 1

Here is how I solved the same issue in Ubuntu 20.04

Locate package libpython3.10-stdlib

$ apt-cache policy libpython3.10-stdlib
libpython3.10-stdlib:
  Installed: 3.10.4-1+focal1
  Candidate: 3.10.4-1+focal2
  Version table:
     3.10.4-1+focal2 500
        500 http://ppa.launchpad.net/deadsnakes/ppa/ubuntu focal/main amd64 Packages
 *** 3.10.4-1+focal1 100
        100 /var/lib/dpkg/status

$ ls -l /var/lib/dpkg/info | grep -i libpython3.10-stdlib
-rw-r--r-- 1 root root   14489 Apr 10 00:26 libpython3.10- stdlib:amd64.list
-rw-r--r-- 1 root root   23536 Mär 24 17:12 libpython3.10-stdlib:amd64.md5sums
-rwxr-xr-x 1 root root    1161 Mär 24 17:12 libpython3.10-stdlib:amd64.prerm

Remove manually the package

$ sudo mv /var/lib/dpkg/info/libpython3.10-stdlib:amd64.* /tmp

Repeat the same steps for libpython3.10-minimal. Then fix the broken packages

$ sudo apt --fix-broken install

Answer 2

I had the same error. I followed the instructions in the first and second answer and I got this:

/var/cache/apt/archives/libpython3.10-stdlib_3.10.4-1+focal2_amd64.debE: Sub-process /usr/bin/dpkg returned an error code (1)

After move this : sudo mv /var/cache/apt/archives/libpython3.10-stdlib_3.10.4-1+focal2_amd64.deb /tmp

It works !
