Hello,

After updating AIX73 TL1 SP2 to TL2 SP1 there was the following error with DNF:

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Previously the command was successful:

I used the current tar.file (dnf_bundle_aix_73.tar)

What is the easiest way to fix the error?

greetings

Ralf

Good morning Ralf,

I ran into the same problem, with some of my AIXes as well. It seems to me that it's really essential to update/upgrade your AIX Toolbox rpms to latest level, before you update to AIX73-TL2-SP1. There I did that, no problems :)

With AIXes on older rpm-levels where I ran into the same problem as you, I ended up in uninstalling/reinstalling all dnf rpms. Else you wont be able to upgrade Python3 to 3.9 level manually, because of dependency hell.

greetings

Matthias

Hello Matthias,

I was now able to solve the problem. The easiest thing is to delete all RPMs and reinstall them.
Luckily the update to dnf_bundle_aix_73 worked on another server.

greetings

Ralf
