So my files are uploaded onto the git-GUI. Pressing commit works fine. The push button is clicked and it ask for my destination repository, so I put https://github.com/myusername/reposistoryname and then press enter, afterwards it asks for my username and password. After those items had been entered in, I get this error message.
Pushing to https://github.com/myusername/reposistoryname
To https://github.com/myusername/reposistoryname
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/emaoll/pnz'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
I have a github account as well as a repository on github.
