Somehow I screwed up ssh on my Raspberry pi that runs ubuntu 20.04 and
my desktop that runs Kubuntu 22.04. When I try to log into one from the
other, I get an error message.
Logging into the desktop from the Pi gives me this error: Load key
"/home/pi/.ssh/id_rsa.pub": invalid format and I'm prompted for a password.
In both of them I deleted id_rsa and id_rsa.pub. Then I tried
ssh-keygen, ssh-copy-id, then tried to log in like ssh-copy-id said to
(ssh
username@ip.address.of.other.machine).
When I tried to log into the Pi from the desktop, the error I get is
Load key "/home/desktop.user/.ssh/id_rsa.pub": error in libcrypto
When try to log into the desktop from the Pi, the error message I get
is Load key "/home/pi.user/.ssh/id_rsa.pub": invalid format
In both cases I'm prompted for a password and I'm able to log in.
The permissions of the files in the .ssh directory on both machines is
the same
-rw------- 1 delboy delboy 564 Oct 21 22:47 authorized_keys
-rwxr--r-- 1 delboy delboy 122 Oct 21 18:27 config
-rw------- 1 delboy delboy 2602 Oct 21 22:43 id_rsa
-rwx------ 1 delboy delboy 566 Oct 21 22:43 id_rsa.pub
-rw------- 1 delboy delboy 364 Oct 21 22:44 known_hosts
In both machines, how can I reset ssh to the state it was in when I
first installed the OS on each machine?
Thanks
