                Can't upgrade/purge redis server on Debian/Ubuntu (apt adapting distros)
              
          
    Situation


Upgrading redis-server is failed with apt upgrade.
apt purge redis-server is failed

The reason for the failure of both apt command above is something is timeout.
Solution (one of)
