[TUTORIAL] How to install Proxmox Backup Client under Ubuntu%

Why not just download it into a password tool? Then keep the password DB safe+replicated to another system and that's it. Can even be automated using APIs if done frequently (different encryption keys per client while providing customers their encryption key as well).

Are there more formats than text? I could not find it in the man-page or the documentation

Code: 
proxmox-backup-client key paperkey [<path>] [OPTIONS]

Generate a printable, human readable text file containing the encryption key.

This also includes a scanable QR code for fast key restore.

<path> : <string>
    Key file. Without this the default key's will be used.

Optional parameters:

--output-format text|html
    Paperkey output format
--subject <string>
    Include the specified subject as title text.

Hi,

we worked around some linking/dependency issues and with version 1.0.8 the dependencies required got reduced, so that it now installs on Bullseye, Ubuntu 20.xy versions and possible other Debian derivatives just fine.

Bash: 
wget http://download.proxmox.com/debian/pve/dists/buster/pvetest/binary-amd64/proxmox-backup-client_1.0.8-1_amd64.deb

# checksum verification
sha256sum proxmox-backup-client_1.0.8-1_amd64.deb
f812593f8f1895fc5cbd5c8b6ec1120a4f863739c7c23aa0f2c15b0f7c59033a  proxmox-backup-client_1.0.8-1_amd64.deb

apt update
apt install ./proxmox-backup-client_1.0.8-1_amd64.deb

is still the above the best way to install the Proxmox Backup Client on Ubuntu 20.04 LTS?

I've tried the official doc as in https://pbs.proxmox.com/docs/package-repositories.html#apt-based-proxmox-backup-client-repository but I get a weird

Code: 
N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://download.proxmox.com/debian/pbs-client buster InRelease' doesn't support architecture 'i386'

after I added the repo:

Code: 
echo "deb http://download.proxmox.com/debian/pbs-client buster main" > /etc/apt/sources.list.d/pbs-client.list
wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
apt update

This is the client

mmmh, I see I had multiarc enabled, I fixed it this way

Code: 
dpkg --print-foreign-architectures
i386

so I removed it with this way

Code: 
# Note that you need to remove all packages of that architecture before doing the following:
dpkg --remove-architecture i386

then the apt installation instruction cited in the Doc https://pbs.proxmox.com/docs/installation.html#client-installation and https://pbs.proxmox.com/docs/package-repositories.html#apt-based-proxmox-backup-client-repository works great on my Ubuntu 20.04:

Code: 
apt-get install proxmox-backup-client


thanks

Since the pbs-client repository is only compiled for amd64 you need to limit the sources.list entry to only amd64. Use the following instead.

Code: 
echo "deb [arch=amd64] http://download.proxmox.com/debian/pbs-client buster main" > /etc/apt/sources.list.d/pbs-client.list

Is there anyway to get the debian package from proxmox anymore? The repository listed above now requires authentication.

NVM, Works fine through apt. Just not a browser.

I'd like to resurrect this thread to post a better way, at least in some cases.

Tested on Mint Victoria, which is based on Ubuntu Jammy (22.04). I couldn't install proxmox-backup-client because only 1.4.8 of libzstd1 was available.

The fix is to add a repo to sources.list that has 1.5.2, and use apt preferences to restrict that repo to only source libzstd1. If we don't do this, then we suddenly have 1000 packages updateable, and we're liable to hose our system.

It is indeed risky to update even just libzstd1, but so far I'm fine, YMMV, no warranty implied.

/etc/apt/preferences.d/proxmox-libzstd1.pref
Code: 
# proxmox-backup-client 3.0.2 requires libzstd1 >=1.5.2

# Don't install from ubuntu kinetic
Package: *
Pin: release n=kinetic
Pin-Priority: -100

# Install from ubuntu kinetic
Package: libzstd1
Pin: release n=kinetic
Pin-Priority: 900

Ansible playbook:
YAML: 
---
- name: Pin libzstd1 to ubuntu kinetic (22.10)
  copy:
    src: proxmox-libzstd1.pref
    dest: /etc/apt/preferences.d/proxmox-libzstd1.pref
    owner: root
    group: root
    mode: 0644

- name: Add ubuntu kinetic (22.10) repository
  apt_repository:
    repo: deb http://old-releases.ubuntu.com/ubuntu kinetic main
    state: present

- name: Add Proxmox GPG repo key
  apt_key:
    url: http://download.proxmox.com/debian/proxmox-release-bookworm.gpg
    state: present

- name: Add Proxmox backup client repository
  apt_repository:
    repo: deb http://download.proxmox.com/debian/pbs-client bookworm main
    state: present

- name: Install Proxmox backup client
  apt:
    pkg:
      - libzstd1
      - proxmox-backup-client
    state: latest
    update_cache: true
    autoclean: true

That reminds me: On nix, proxmox-backup-client is available. Related, proxmove (for migrating VMs between non-clustered hosts) is also there.
