>From your log: /var/lib/dpkg/info/python-six.postinst: 6: pycompile: not found
The missing binary pycompile is of pkg:python2 And python-six in Focal has: Depends: python2:any (<< 2.8), python2:any (>= 2.7~) According to your log you should have python2-minimal:amd64 2.7.17-2ubuntu4 Which provides the missing binary. So everything should work, but it didn't. Could you check the following things on your system: # which pycompile /usr/bin/pycompile # dpkg --verify python2 # dpkg -S pycompile ... python2-minimal: /usr/bin/pycompile # ll /usr/bin/pycompile -rwxr-xr-x 1 root root 11895 Mar 13 2020 /usr/bin/pycompile* If your output is different that might be an indicator what is wrong. But with the logs so far I fail to see the root cause. ** Changed in: six (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903484 Title: package python-six 1.14.0-2 failed to install/upgrade: installed python-six package post-installation script subprocess returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/six/+bug/1903484/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
