[SOLVED] synchronization of all databases failed

Bonjour,

 $sudo pacman -Syu
:: Synchronizing package databases...
error: synchronization of all databases failed (unable to lock database) 

 $uname -snr
Linux  leloupArch 6.17.7-zen1-1-zen
$sudo pacman -Q pacman
pacman 7.0.0.r6.gc685ae6-6 

It seems that pacman is busy with a task that I can't kill.

 $ps aux | grep pacman
Leloup      6100 30.0  0.1   6976  4308 pts/0    S+   11:48   0:00 grep --color=auto pacman 

Furthermore, Linux is slower than usual.
Do you have any idea to solve this issue?
Regards,
Leloup

Dear system72,
Thank you.
In first; I did in root mode:

 # fuser /var/lib/pacman/db.lck 

Still in root mode:

 # rm /var/lib/pacman/db.lck 

That fix my issue.
Regards,
Leloup
