# Out-of-date generic Linux of build

## It was sudo wget https://repo.jellyfin.org/releases/server/linux/stable/combined/jellyfin_10.8.9_amd64.tar.gz ---
> 
> - (...)jellyfin_10.8.**9**_(...)
 - (...)jellyfin_10.8.**13**_(...) ---
## The correct is sudo wget https://repo.jellyfin.org/releases/server/linux/stable/combined/jellyfin_10.8.13_amd64.tar.gz

## I also corrected the other places where it was " 10.8.*9* " to " 10.8.*13* "
