Multi account with ssh keys on a device https://www.techaddressed.com/tutorials/add-verify-ssh-keys-gitea/

• Linux The permissions have to be set like this This means that the permissions on that file are also set incorrectly, and can be adjusted with this:

  sudo chmod 644 ~/.ssh/known_hosts : it means read and write for user and read for group and others

  Finally, you may need to adjust the directory permissions as well:

  sudo chmod 755 ~/.ssh : it means read,write,execute for user, read,execute for group and others

  This should get you back up and running.  

  The keys need to be read-writable only by you:

  chmod 600 ~/.ssh/id_rsa

  Alternatively, the keys can be only readable by you (this also blocks your write access):

  chmod 400 ~/.ssh/id_rsa

  600 appears to be better in most cases, because you don't need to change file permissions later to edit it. (See the comments for more nuances)
