As far as I can tell, these are the methods apt uses to get information from the repositories that is listed within sources.list and within the sources.list.d directory. The number of subprocesses almost matches the number of sources there - in reality there are 14 listed, not 13 as is seen in the ps output. I can find one entry that starts with mirror+file, but otherwise there are 13 https entries. So that last line I am not sure what is doing.
Anyways, it seems to me that it gets stuck somewhere updating the repositories list. Right now, I’m stuck with three questions:
I’m still unsure as to whether it would be safe to kill the process, as I could imagine that having a corrupted depencies files could be really bad?
Also, would killing the process automatically release the lock, or would I need to remove that myself after?
Is there any reason to believe that this would even work, seeing as this happens everytime on boot. I imagine that if I kill the process, delete the lock and try to run sudo apt update I just end up the same place again.
