  8. [SOLVED] lxc upgrade to bullseye trouble

    - i had a left over from testing eth1 in interfaces . removing that fixed . - the cause of my other issue is probably due to removing /etc/apt/sources.list.d/turnkey.list some years ago - then not getting updates. thank you

  13. [SOLVED] lxc upgrade to bullseye trouble

    after rebooting the pve host the lxc got a network address [ probably restarting a systemd unit would have done the same thing.] however this still freezes: systemctl status and media server does not work. I'll try starting in debug mode later on.

  15. slow migrations
