OpenSuSE Tumbleweed: after installing from ISO, be sure to disable/remove the ISO repo

Posted by jpluimers on 2016/10/26

TL;DR: OpenSuSE Tumbleweed – after installing from ISO, be sure to disable/remove the ISO repo.

A while ago I had a weird thing on my OpenSuSE Tumbleweed system while upgrading (yes, zypper dist-upgrade is the recommended way to update Tumbleweed): it would complain in this way zypper dup indicates python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5:

# zypper dup
Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command.
Loading repository data...
Reading installed packages...
Computing distribution upgrade...

Problem: python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5, but this requirement cannot be provided
 Solution 1: Following actions will be done:
  deinstallation of python3-urllib3-1.15.1-2.1.noarch
  deinstallation of python3-wheel-0.29.0-2.1.noarch
  deinstallation of speedtest-cli-0.3.2-4.3.noarch
  deinstallation of python3-six-1.10.0-4.1.noarch
  deinstallation of python3-pycparser-2.14-2.1.noarch
  deinstallation of python3-pyasn1-0.1.9-2.1.noarch
  deinstallation of python3-pyOpenSSL-16.0.0-3.1.noarch
  deinstallation of python3-idna-2.1-1.1.noarch
  deinstallation of python3-chardet-2.3.0-1.4.noarch
 Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch
 Solution 3: break python3-urllib3-1.16-1.1.noarch by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/3/c] (c): 

What eventually – with help from the excellent help by DimStar on the #openSUSE-factory IRC channel – led to the solution was the part Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch.

But first let’s look at the installed versions and repos:
