Installation

Install Cloud-PBS TUI and its dependencies with the install script or manually.

Last updated: May 18, 2026

Cloud-PBS TUI is available for Linux amd64 (x86-64), the only architecture for which Proxmox ships proxmox-backup-client. On any other architecture the backup client does not exist and the tool cannot do anything.

The install script sets up Cloud-PBS TUI and its dependencies (proxmox-backup-client, FUSE):

curl -fsSL https://cloud-pbs.com/downloads/cloudpbs-tui/install.sh | sudo bash

The script:

  • checks the architecture and stops if it is not amd64;
  • on Debian and Ubuntu, adds Proxmox’s official pbs-client repository and installs proxmox-backup-client and fuse3 through apt;
  • on other distributions, installs the static proxmox-backup-client-static binary published by Proxmox, then FUSE through the detected package manager;
  • installs cloudpbs-tui into /usr/local/bin.

Choosing the Proxmox client version

The proxmox-backup-client must be compatible with your PBS server version. The script defaults to the bookworm suite (PBS server 3.x). For a PBS 4.x server, specify the trixie suite:

curl -fsSL https://cloud-pbs.com/downloads/cloudpbs-tui/install.sh | sudo PROXMOX_SUITE=trixie bash

Manual installation

You can also install the binary on its own. Download the archive and its checksum:

  • https://cloud-pbs.com/downloads/cloudpbs-tui/cloudpbs-tui-linux-amd64.tar.gz
  • https://cloud-pbs.com/downloads/cloudpbs-tui/SHA256SUMS

Verify the archive, then extract it:

sha256sum -c SHA256SUMS
tar xzf cloudpbs-tui-linux-amd64.tar.gz
sudo install cloudpbs-tui /usr/local/bin/

In this case, proxmox-backup-client and fuse3 still have to be installed separately:

  • Debian / Ubuntu: add Proxmox’s pbs-client repository, then apt install proxmox-backup-client fuse3.
  • Other distributions: install the static proxmox-backup-client-static binary from download.proxmox.com, and fuse3 through your package manager.

Verify the installation

Launch the tool:

cloudpbs-tui

The Home screen appears. If proxmox-backup-client is missing, a banner says so at the top of the interface: real backups will only be possible once the client is installed.

Updating

To update Cloud-PBS TUI, run the install script again: it fetches the latest published version. On Debian and Ubuntu, proxmox-backup-client is updated along with the rest of the system by apt.
