Install Failure Due to Missing lz4 Dependency on Debian 11

[RedlineTriad]

Using this role on a fresh debian 11 server fails, see error logs here: https://github.com/RedlineTriad/private_server/actions/runs/10395280145/job/28786958496#step:6:102

It seems a commit addressing this is already being worked on but not released or fully working yet. Just writing this issue for traceability, updates, and googleability. Will see if I can work around it on my own for now.

I also took 5 minutes to try and upgrade to debian 12 but it seems I get the same error there :(

I can confirm that using the latest commit at the time of writing fixes this issue for debian 12:

roles:
  - name: borgbase.ansible_role_borgbackup
    src: git+https://github.com/borgbase/ansible-role-borgbackup.git
    version: 0e5e8766264233788eeb0abb1d48e854cedcf7aa

I'm using this on Debian 12, but set it to use the distro package and NOT build from source. Maybe using the distro package would be a better default?

I found https://github.com/borgbackup/borg/pull/8117 and the bundled software was removed, meaning you have to provide liblz4, libstd, and libxxhash outside of Borg 👍
