PTY allocation request failed on channel 0

[VVStz]

Hi,

I'm running borgbackup in client/server mode like borg -pv create ssh://user@host:port/Repo::backup /to/path

and it works pretty well.

But after if I try to connect to the ssh server ssh user@server I get

PTY allocation request failed on channel 0

Did I do something wrong ? if not I'll convert this into an Issues.

Thanks

I figured it out. :)

Please outline the solution in case someone else hits the same issue

It was because that user has command="borg serve --restrict-to-path /path/to/repo" ssh-rsa AAAAB in host ~/.ssh/authorized_keys
Then I suppose as long as borg serve is running no possibility to use tty/pts

As you enforce that only borg serve will be used for that key, there is no way to use that key for interactive login.
