thats an simple debian package with following install:
curl -fsSL "https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg" -o "/etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg"
cat <>/etc/apt/sources.list
deb http://download.proxmox.com/debian/pbs bookworm pbs-no-subscription
EOF
apt-get update
apt-get install -y proxmox-backup-server

do it manually on this lxc and check

Okay, I am sorry but I didn't actually use the default settings instead I set the hostname to pbs from the default proxmox-backup-server and the remaining settings keep the same. Now that I try the real default settings the script runs fine and I have my pbs installed and setup nicely.

But I wonder why the issue occur when I try to use a different hostname?

[MickLesk]

idk, the hostname is an network thing. maybe your router dont allow this as special name or proxmox himself

[yushisora]

Alright, that make sense. Thanks for the help.

This issue still exists. I used the advanced install to set a MAC address and VLAN, left the hostname alone. But I still have the exact same issue.

edit: also using verbose mode

Tried to follow @MickLesk 's instructions, but it's still stuck:

I think this issue should be reopened.

I am trying to install with advance settings and if I try to install it a privileged container is always stuck, once I tried on verbose too, and it's stuck on the same place, if it's not verbose it's stuck under Installing Proxmox Backup Server. I tried multiple times, different nodes, and always the same, can stay hours there. But I just use default settings and nothing changes, it works like a charm.

[yushisora]

@MickLesk I think we should reopen this issue. I also edited the original post to show that I am using advanced setting instead.

[MickLesk]

@tremor021 can you check?

[tremor021]

all is good here

[SirMartin]

Yea, as unpriviliged, the issues are with advanced settings, in my case trying to have one with privileges

[tremor021]

All ok with priviledged LXC

[MickLesk]

Work fine Here, both Settings
