SSH stopped working (ubuntu 18.04)

mk_street

I used to have SSH working for all my repositories on my desktop PC.

Something seems to have updated in Ubuntu a few months ago and now SSH no longer works. I didn't report it here right away, but now it has become increasingly annoying.

On my laptop, I can still use SSH to access all my repositories the same as always.

But on my desktop PC, SSH has stopped working.

For example, when I try to do a git push, it hangs for several minutes then eventually comes back with this error:

Pushing to git@bitbucket.org:XXXX/XXXXX.git
ssh: connect to host bitbucket.org port 22: Network is unreachable
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

 

When the problem first occurred, I tried the SSH troubleshooting FAQ, restarting SSH  on the PC, and so forth.

 

I am not an SSH expert.  I just don't know what to try to diagnose the situation or get more information to lead to a solution.

"Network is unreachable" simply means that your client machine cannot get to the target over your network.

This is almost always caused by a local network problem - your machine is simply not on the internet.

Try

ssh -vvv <target>

This gives you a suprising (and yet boring) information about the connection!
