The root cause of this problem is Zentyal who provide an updated version of libapt-pkg5.0 in their repositories (version 1.5.1), but no updated version of the apt package (which will be taken from the Ubuntu repositories, currently version 1.2.29). These two packages do not fit together.
Workaround: downgrade libapt-pkg5.0 to the Ubuntu version (and mark that package not to be updated to the Zentyal version again) Long term solution proposal: Zentyal have to reassess and correct the contents of their repositories. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1644643 Title: apt failed to run due to link time reference error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1644643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
