user created by borgserver can't access their home directory

[deckname]

This is the important part from the log:

2021-05-31 04:07:45,882: DEBUG - + set +e
2021-05-31 04:07:45,882: DEBUG - + borg init -e repokey ssh://xxx@xxx:22/~/backup

I also can't manually ssh into the user, even though the authorized_keys is set properly, it is a new user and both on borg client and server new install of the app.

If I su to the user on the borgserver it gives a permission error su: warning: cannot change directory to /home/xxx: Permission denied

Both running YunoHost 4.2.5.2 (stable).

I got it to work. What was needed:

sudo chown backupuser /home/backupuser on the borgserver machine so that the backupuser can access their home and

chmod 600 .ssh/id_borg_ed25519 chmod 600 .ssh/id_borg_ed25519.pub as root on the machine that you want to be backed up, without this the machine can't ssh into the other one.

So it did work, I even checked the backups if they had the expected data. It worked when started with sudo systemctl start borg and it worked when it was started automatically for the first time. Now it fails with this error:

I think the error now is with borg_ynh not borgserver_ynh
