Hey Vasilisc,

It seems then that ssh is using hardcoded paths like /home/$USER/.ssh
for looking by default to id_rsa file and not using $HOME. Multiple ways
to get that fixed:
* reading the openssh-client code and fix it to use $HOME (and so, it
will use your snap $HOME)
* use ssh -i (look at the manpage for ssh) to point to an identity file
directly

Cheers,
Didier
