Avron · November 9, 2022, 11:33am

I tried a manual backup, it failed nearly immediately (well, after taking time stopping services).

Here are the logs:

After that, diagnostics show many services are not working, e.g. ejabberd, coturn, postfix. I saved logs ahead and after if that is usefull (it is to long to post here). I can make a bug report if useful.

Do you see any disk or filesystem errors in journal or dmesg? Could you try again after removing /root/.cache/borg folder?

No but I rebooted after the failure in order to re-start all services.

It is a remote backup, not local disk. On the remote machine, I have set “ForceCommand internal-sftp” for the user. It was working previously. When logged in as admin user to the freedombox, sftp in command line to the remote machine works.

Sure, doing that in a short moment.

EDIT: I tried setting a backup location on another remote machine, it fails with a message saying “Authentiucation public key of the server could not be verified”. Is it something in “known_hosts”? Of which user?

sunil · November 9, 2022, 4:49pm

When a new backup location is added, we show in the interface the public key fingerprint of the server and ask user to verify it. Try removing the remote location and adding a new location instead of editing the location.

It worked ! Many thanks ! (this is a huge relief for me).

When trying to configure another remote machine for backup, I realized I can’t remember whether I have set encryption for backups and I can’t find anything for that in my password database.

I need to look at that.

Avron · November 9, 2022, 4:58pm

I did but it says (my own translation to English):

Add a new remote ssh repository (green background)
SSH server already verified (green background)
Authentication public key of the server could not be verified (red background)
Repository removed (red background).

I think I re-installed the OS on the remote machine and did not keep the host keys, so probably the freedombox has stored the host key for it somewhere and it does not match with the new host key. I looked in /root/.ssh, there is nothing there. Not sure where to look.

Edit the file /var/lib/plinth/.ssh/known_hosts
