Unable to update Unifi Network Appliance

[julred]

Dear all,

I wanted to update my Unifi Network Appliance LXC by using this updater script:
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/unifi.sh)"

I was running this command inside unifi lxc. Afterwards it shows, upgrade successful, but the old unifi version is still active - or i guess the latest version was not installed successfully.

Installed Unifi Version: 7.3.83
Latest Unifi Version: 9.0.108

root@unifi:/etc# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye

If I manually try to apt-get update in lxc, I got the following issue:

Understood. Is it sufficient to back-up from "System->Backup (No Limits)". Or are there any better ways?
