Today I installed these latest python packages on an AIX 7.3.2.1 system:

python3-six-1.13.0-1.noarch

python3-libdnf-0.39.1-64_50.ppc

python3-gpg-1.13.1-100.ppc

python3-dnf-plugins-core-4.0.16-64_50.ppc

python-pycurl-7.43.0-1.ppc

python-devel-2.7.18-3.ppc

python3-pyyaml-5.4.1.1-1.ppc

python3-devel-3.7.15-2.ppc

python3-test-3.7.15-2.ppc

python-iniparse-0.4-1.noarch

python-urlgrabber-3.10.1-1.noarch

python3-dateutil-2.8.0-1.noarch

python-2.7.18-3.ppc

python3-libcomps-0.1.11-100.ppc

python3-hawkey-0.39.1-64_50.ppc

python3-dnf-4.2.17-64_51.ppc

python3-librepo-1.11.0-100.ppc

python-tools-2.7.18-3.ppc

python3-3.7.15-2.ppc

python3-docs-3.7.15-2.ppc

python3-tools-3.7.15-2.ppc

and now yum (which uses python) does not work, giving this error:

# yum update

Memory fault(coredump)                      [===                                   ] ---  B/s |   0  B     --:-- ETA

Also, errpt shows many of these errors:

Does anyone have a suggestion for a fix? Thank you!

yum is not supported on 7.3 - use dnf instead.. this site had some earlier discussions about dnf, and there is a dnf install script you can download

I tried using the dnf install script but ran into this:

# ./dnf_aixtoolbox.sh -y

Attempting download of dnf_bundle_aix_73.tar ...

lwp-download: 500 Can't connect to public.dhe.ibm.com:80 (Connection refused)

Failed to download dnf_bundle_aix_73.tar

----------------------------------------------------------------------------------------------------
Is there a current issue with that site?

Thanks

Not entirely sure how to "fix" that - but, if the old version of python is still there, you can try editing the "yum" script
and change the line from

#!/usr/bin/python

to point to the original version, say

#!/usr/bin/python3.6

There may be more scripts that got broken by the python update, so, alternatively, you can relink "/usr/bin/python" (and possibly "/usr/bin/python3") to the original version, whatever it was.

I suspect that adding missing packages to the new python could help as well, but I am not a python expert, don't know how to (easily) figure out what's missing and where to get it ( pip install ? )
