I started a new Project a GitLab. After that i created a Repo, all works! Then i generated a public key with (ssh-keygen -t rsa -C "my registrated email at git"). I added my Private Key to my personal GitLab Profile.
But when I want to test my connection with
git push --set-upstream origin master
Git is telling me that:
Host key verification failed. fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
I'am using Ubuntu 16.04 LTS
Thanks in advance!
