I have been trying to push my work on github but I get this error :
PS C:\Users\xxx\Desktop\wiki\wiki> git push origin --all
To https://github.com/me50/xxx.git
! [rejected] web50/projects/2020/x/wiki -> web50/projects/2020/x/wiki (fetch first)
error: failed to push some refs to 'https://github.com/me50/xxx.git'
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.
