Install the backup client on ubuntu 22.04 server?

What if we use libzstd package from another sources, for example,
Code:
wget https://launchpad.net/ubuntu/lunar/amd64/libzstd1/1.5.4+dfsg2-4
so we can use pbs-client v3 (installation was successful in my case)?
I know this isn't recommended, so as having outdated libssl package in the system.
Is there some heavy consequences with third party libzstd package?
 
it depends on the library and their stability guarantees, and how it is packaged.
 
As of OCT 2023, there seems to be an updated release of "libssl1.1" and we can also use a repo instead of using dpkg to manually install the relevant .deb file...

Bash:
# Install the Debian Bullseye repo key first (this repo is "closest" to Ubuntu 22.04 "jammy")
wget https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg
# Setup the PBS client repo
echo "deb [arch=amd64] http://download.proxmox.com/debian/pbs-client bullseye main" | sudo tee /etc/apt/sources.list.d/pbs-client.list
# Setup the LibSSL1.1 client repo from the Ubuntu "focal" security repo (apparently it's not yet available for "jammy")
echo "deb [arch=amd64] http://security.ubuntu.com/ubuntu focal-security main" | sudo tee /etc/apt/sources.list.d/focal-security.list
# Update repos and install PBS client
apt update && apt install -y proxmox-backup-client

...or as a one-liner:

Bash:
wget https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg; echo "deb [arch=amd64] http://download.proxmox.com/debian/pbs-client bullseye main" | sudo tee /etc/apt/sources.list.d/pbs-client.list; echo "deb [arch=amd64] http://security.ubuntu.com/ubuntu focal-security main" | sudo tee /etc/apt/sources.list.d/focal-security.list; apt update && apt install -y proxmox-backup-client

The PBS client installation will auto-fetch LibSSL1.1 and other dependencies.

The above will eventually install v2.4.1 of the PBS client.

nope,

bad news: tried with ubuntu 22.04 lts and bookworm repsoitories - still received "proxmox-backup-client : Depends: libzstd1 (>= 1.5.2) but 1.4.8+dfsg-3build1 is to be installed"
but good news: tried with ubuntu 24.04 lts and bookworm respositories -- successful installation without any hassle

to PROXMOX-Team: is it possible to update your documentation ?
 
still have found no joy in getting this to work on 24.04. Will be waiting for when it is ready.
