Comment 2 for bug 1786944

According to the attached the problem is older than 2018-08-02. We would need logs from when the problem started happening to understand what caused it.

Please try running the following command and let us know if this fixes the issue:

    apt-get -f install

If it doesn't, please inspect /var/log/apt/term.log* and /var/log/apt/history.log* and attach the relevant ones (the ones that include the first mention of a problem when installing/upgrading packages). If in doubt, the first archive should be enough:

    /var/log/apt/term.log.1.gz
    /var/log/apt/history.log.1.gz
