Nala broken due to python-apt udpate

[eriefisher]

After a nala upgrade this morning installed a new kernel I rebooted. I tried to remove the older kernel once I was back up but nala is failing. Unfortunately I didn't get a good look at what was being installed/updated. It was a short list though.

python-apt is broken, please be patient with an update!

apt update and apt full-upgrade still working!

Edit @eiriefisher Sorry I changed the headline!

Apology not needed. The title should reflect the bug propery.

Looking at the logs it does confirm that a python update is the cause.

Well, I downgraded python3-apt and nala works again.

For those who need nala desperately, https://snapshot.debian.org/package/python-apt/2.7.0/#python3-apt_2.7.0:2b:b1

But be careful with that axe, [...], it can kill your pet.

Thanx for this info. I don't think this axe is sharp enough to kill the pet. Anyway I don't really see a reason to downgrade. Apt is doing the job pretty well until the bug is fixed.

python3-apt got a fix, so nala works again, and definitely other programs too!

apt policy python3-apt
python3-apt:
  Installed: 2.7.3
  Candidate: 2.7.3

With the next mirror sync, it should be there.

Thanks for the notification. I'll take python-apt off "hold".
