Hey there,

for a couple of days my proxmox Hypervisor isn't able to update apt :confused:.

This is my current output:

Code:
E: Could not get lock /var/lib/apt/lists/lock. It is held by process 3885896 (apt-get)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/


When I kill the process and run apt update its getting stuck on the following screen for hours...

Code:
root@proxmox1:~# apt update
Hit:1 http://security.debian.org bookworm-security InRelease
Hit:2 http://ftp.de.debian.org/debian bookworm InRelease                             
Hit:3 http://download.proxmox.com/debian/pve bookworm InRelease                     
Hit:4 http://ftp.de.debian.org/debian bookworm-updates InRelease
0% [Working]


Does anybody got an idea what could go wrong?

do you have other repositories configured beside those four? It might be stuck connecting to/querying the next one.
 
What is the output of ps aux | grep "apt\|dpkg"? Can you run strace apt update &> /tmp/apt-strace.log and share the resulting file (or tail -n 100 /tmp/apt-strace.log if it's too big)?
 
Heyho,
sorry for the late reply! Private life was turbulent :eek:

What is the output of ps aux | grep "apt\|dpkg"?

Make shure all apt and dpkg processes are killed.

Find all remaining lock files from those processes

find /var -type f -name lock

and remove them (only of they Belang to apt and dpkg)

Try apt Update

and apt upgrade again
 
Thats the Problem ... nothing is locked! When I remove all sources from the apt list its working fine. It seems to me that my Proxmox is not able to proccess the packages
 
Okay, a new update. After making sure no process is running I noticed: apt-update takes 30 Minutes to fetch all! That is way to long ... I'll change some sources maybe :/
 
Hey there,
found the issue. One of the SystemSSD war failing, so the IO Load was beyond good and evil. Swapping the SSD fixed everything.
