Public bug reported: My /var/cache/apt/archives directory is mounted as a tmpfs partition, therefore after a fresh boot, the directory is empty.
In such a situation, synaptic fails to install any package with the following error: E: Could not open lock file /var/cache/apt/archives/lock - open (2: No such file or directory) E: Could not open file descriptor -1 E: Unable to lock the download directory Workaround to repair synaptic for current session: sudo mkdir -p /var/cache/apt/archives/partial sudo touch /var/cache/apt/archives/lock sudo chmod 640 /var/cache/apt/archives/lock synaptic should silently create those files if they are missing, instead of failing, like apt does. ** Affects: synaptic (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1591620 Title: Synaptic can't install a package if /var/cache/apt/archives does not exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/1591620/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
