Something that would help us a lot to understand the problem would be this:

  1. Open the application called ‘Terminal’
  2. In this application run the command:

rm -f eos-fix-ostree-repo
wget https://raw.githubusercontent.com/endlessm/eos-meta/master/eos-tech-support/eos-fix-ostree-repo
chmod +x eos-fix-ostree-repo
sudo ./eos-fix-ostree-repo
