I think that the problem somehow involves perl being upgraded from 5.22.1 to 5.26 but 5.22.1 still being used when the trigger for doc-base is invoked.

I have made a pre-upgrade btrfs snapshot. I plan to revert to it then uninstall doc-base and re-run the upgrade, then re-install doc-base. I plan to keep the snapshot if any developer would like me to test upgrade again with a fixed package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869410 Title: package doc-base 0.10.7 failed to install/upgrade: installed doc-base package post-installation script subprocess returned error exit status 10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/doc-base/+bug/1869410/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
