Update Turnkey Linux LXC Debian Conatainer running on Proxmox VE from Buster to Bullseye

The recommended way of upgrading is to save your changes with tklbam, use a fresh and updated Turnkey image and reimport all your changes. When you do not want to go this way and just update the Debian version you can follow this howto.

This will not update the Turnkey version.

HowTo

• Proxmox Upgrade vom 6.x to 7.x
• Update current system
  • apt update
    • apt upgrade
• Update Repositories
  • sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list.d/*
• Update repo signed keys
  • Turnkey Forum

codename=bullseye
key_dir=usr/share/keyrings
url=https://raw.githubusercontent.com/turnkeylinux/common/master/overlays/bootstrap_apt
for repo in main security; do
    full_path=$key_dir/tkl-$codename-$repo
    keyring=$full_path.gpg
    keyfile=$full_path.asc
    wget -O /$keyfile $url/$keyfile
    gpg --no-default-keyring --keyring /$keyring --import /$keyfile
    rm /$keyfile
done

• Update to new version
  • apt update
  • apt dist-upgrade
    • keep current configurations
  • apt autoremove to clean up old packages
• reboot and check services

Troubleshooting

Service in container is failing to start with “NAMESPACE” Error

For this container the feature nesting has to be enabled on the conatiner on the Proxmox host.

Redis not starting because it cannot find it’s run folder

This was giving me headaches when updating Turnkey Nextcloud V16.1 from Debian 10 to Debian 11. After the Update Redis was not starting as daemon anymore because it was not able to create it’s pid and sock file in /var/run/redis/.

Starting redis as non deaemon was working fine.

/var/run/redis/ was not present after starting the machine after the update. Despite it should be created when looking at /etc/init.d/redis-server it was not there.

Manually creating the folder worked. But it was deleted on restart of the service or reboots.

Solution was to create a file /usr/lib/tmpfiles.d/redis-server.conf with content:

d /run/redis 0755 redis redis

Now on each reboot the folder /var/run/redis/ is created and permissions are set properly.
