Fingerprint cannot be generated while adding new ssh key in GitLab

Posted on Posted in development

This applies to Windows only machines.

I have GitLab running and was adding a new ‘ssh key’ from windows that was generated using a standard ssk-keygen command but was reciving following error:

“Fingerprint cannot be generated”

Command used to generate key:

 ssh-keygen -t rsa -C "gbugaj@localhost" -b 4096

This produces a key in ‘id_rsa.pub’ file, from there I cated that file and copies the content of if by ‘HIGHLIGHTING’ directly in the command window.

This is the result that got when pasted it

As you see here lines are split, this is the problem. To solve this we just need to open the file in some editor and copy it from there so all the text is on one line.
