I'm trying to run PBS v2.x directly in a LXC running Debian 11. Already have a PBS v1.x instance running in another LXC running Debian 10, so I thought to give it a try with the new version... What steps did a take? Here a summary:
  1. create lxc using template debian-11-standard_11.0-1_amd64.tar.gz
  2. resources: arch: amd64 / cores: 2 / hostname: prxmxbs / memory: 2048 / mp0: /media/usb-hdd/pbs,mp=/media/usb-hdd / net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=[redacted],ip=dhcp,type=veth / ostype: debian / rootfs: local-lvm:vm-900-disk-0,size=16G / swap: 1024
  3. options" privileged [also tried unprivileged] / features: none
  4. inside the lxc:
    - wget https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg
    - edit /etc/apt/sources.list.d/pbs-enterprise.list
    #deb https://enterprise.proxmox.com/debian/pbs bullseye pbs-enterprise
    - edit /etc/apt/sources.list
    deb http://download.proxmox.com/debian/pbs bullseye pbs-no-subscription
    - apt update && apt install -y proxmox-backup [also tried with proxmox-backup-server]
  5. tried https://server-ip:8007/ - but got a "ERR_CONNECTION_REFUSED"
Code:
# systemctl status proxmox-backup-proxy.service

Where is that rrdb stat dir supposed to be created and why is it failing? Any help is greatly appreciated!

yeah it seems to be a bug in how (or better: where) we create the directory

you can workaround by creating the directory: '/var/lib/proxmox-backup/rrdb' and make it belong to the 'backup' user and group by doing:

Code:
chown backup:backup /var/lib/proxmox-backup/rrdb

same bug today, and same "Failed to start Proxmox Backup API Proxy Server"
and also this workaround works for me

thanks for the help
