front end lock error during dpkg install

linux-man · 04-22-2023, 08:17 PM

Code:

$sudo -i
[sudo] password: 
[root@host]─[~]
#dpkg -i min_1.3.1_amd64.deb
dpkg: error: dpkg frontend lock was locked by another process with pid 30757
Note: removing the lock file is always wrong, and can end up damaging the
locked area and the entire system. See <https://wiki.debian.org/Teams/Dpkg/FAQ>.

I assume you want to know why this happening and how to fix it?

Since the error message gives you a PID number, you can use that to find out the running process with

Code:

ps -p 30757 -o comm=

.
Then you can kill that process if it is still running to free up the lock. If there is no process running, then you should be fine to remove the lock file.

not to speak about the help printed, see https://wiki.debian.org/Teams/Dpkg/FAQ. Did you check the very first entry?
