[pve-devel] [PATCH v6 proxmox-backup 5/6] add upgrade_repositories call

[Fabian Ebner]

Signed-off-by: Fabian Ebner <f.ebner at proxmox.com>

Note that the release_upgrade function is available with proxmox-apt 0.1.1
(but disabled) so this can be applied to the master branch as well.

Changes from v5:
    * limit to Superuser instead of SYS_MODIFY
    * use new/renamed release_upgrade function from library.
    * error if not all files could be parsed
