proxmox-backup-client not using ~/.config/proxmox-backup/encryption-key.json by default

[M.D. Klapwijk]

Ran into the following issue; proxmox-backup-client does not seem to use the default ~/.config/proxmox-backup/encryption-key.json if no --keyfile parameter is given for mount command:

root@mdk-tst-01:~# proxmox-backup-client mount host/mdk-tst-01/2022-09-20T23:00:01Z etc.pxar /mnt
Error: missing key - manifest was created with key xx:xx:xx:xx:d4:db:6c:34

The file is there and works correctly with the --keyfile parameter defined to it:

root@mdk-tst-01:~# proxmox-backup-client mount host/mdk-tst-01/2022-09-20T23:00:01Z etc.pxar /mnt --keyfile ~/.config/proxmox-backup/encryption-key.json
Encryption key file: '"/root/.config/proxmox-backup/encryption-key.json"'
Encryption key fingerprint: 'xx:xx:xx:xx:d4:db:6c:34'
FUSE library version: 3.10.3

version:

root@mdk-tst-01:~# dpkg -l proxmox*

Note

If you do not specify the name of the backup key, the key will be created in the default location ~/.config/proxmox-backup/encryption-key.json. proxmox-backup-client will also search this location by default, in case the --keyfile parameter is not specified.

mhmm... normally it should search the $XDG_CONFIG_HOME locations

can you post the output of

strace -fyy proxmox-backup-client mount host/mdk-tst-01/2022-09-20T23:00:01Z etc.pxar /mnt

(caution, this can be long, and possibly needs to be anonymized)

ah ok thanks, after debugging, it seems that we don't use the same codepath for 'proxmox-backup-client mount' and that doesn't search in the $XDG_CONFIG_HOME path
the other commands (backup/restore/etc) should all do that

would you mind opening a bug, so we can track it easier? https://bugzilla.proxmox.com
