What I'm trying to do and why

I'm trying to initialize a repo with sudo borgmatic init --encryption repokey on a Hentzer Storage Box. I'm following the steps on https://torsion.org/borgmatic/docs/how-to/set-up-backups/#initialization

Steps to reproduce (if a bug)

Config:

location:
    source_directories:
        - /home
        - /etc
    repositories:
        - ssh://u11111@u11111.your-storagebox.de:23/./backups/pc
    exclude_patterns:
        - '*.pyc'
        - /home/*/.cache

storage:
    encryption_passphrase: MyPassphrase
    ssh_command: ssh u11111@u11111.your-storagebox.de -F /home/user/.ssh/config

retention:
    keep_daily: 7
    keep_weekly: 4
    keep_monthly: 6
    keep_yearly: 1

consistency:
    checks:
        - repository
        - archives

Actual behavior (if a bug)

sudo borgmatic init --encryption repokey --verbosity 2

Need some help? https://torsion.org/borgmatic/#issues

Expected behavior (if a bug)

However, when I run borg init --encryption repokey --debug ssh://u11111@u11111.your-storagebox.de:23/./backups/pc manually it works correctly.

Other notes / implementation ideas

I'm not entirely sure what's going on here, but have you tried directly running the Borg command that borgmatic is initially tripping up on? Example:

borg info --debug ssh://u11111@u11111.your-storagebox.de:23/./backups/pc

Standalone borg commands were working fine.

Anyway, I upgraded my Ubuntu to 20.04 and installed borgmatic through apt (although at version 1.5.1). Everything seems to work now.

The only other thing I changed was ssh_command option in preferences. Previously I had it set to ssh u11111@u11111.your-storagebox.de -F /home/user/.ssh/config -p 23 and it's possible the duplicated user@hostname part caused problems. You can see it in the SSH command line: section of my debug log above.
