Package: unattended-upgrades Severity: important Dear Maintainer,
While I do understand the importance of having upgrades being installed automatically to keep the system updated, unatended-upgrades is blocking my own attempts to upgrade, install or remove packages. Its process runs automatically, so more often than not, when I try to do any of the mentioned tasks I'm confronted with the following message: mosca: /home/fmneto#> sudo apt upgrade E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it? Taking a careful look, the following processes are running that are using those locks: mosca: /home/fmneto#> ps aux | grep apt root 7209 0.0 0.0 2388 756 ? Ss 08:24 0:00 /bin/sh /usr/lib/apt/apt.systemd.daily install root 7221 0.0 0.0 2388 1520 ? S 08:24 0:00 /bin/sh /usr/lib/apt/apt.systemd.daily lock_is_held install fmneto 10803 0.0 0.0 6076 824 pts/0 S+ 08:28 0:00 grep apt I take two issues with this. 1. Although the task being run is listed as "daily", this lock is in place no matter what the time I try to run apt. 2. Because of this I need to kill those processes and remove the locks in order to be able to actually perform the tasks I need (e.g. install/remove packages) As I said before, I completely understand the necessity and usefulness of having unattended upgrades, but as of now I prefer to remove the package and upgrade my system manually. This way at least I can install packages when I actually need to. I propose that some kind of countermeasure is implemented in dpkg, making it possible for the processes related to unattended upgrades to abort their actions and release the locks when it detects that dpkg is trying to perform some task that was started by the user.
