  1. Open the application called ‘Terminal’
  2. In this application run the command:
rm -f eos-update-flatpak-repos
wget --quiet https://raw.githubusercontent.com/endlessm/eos-boot-helper/e510a0b4/eos-update-flatpak-repos
chmod +x eos-update-flatpak-repos
sudo ./eos-update-flatpak-repos
flatpak install flathub org.libreoffice.LibreOffice -y
flatpak update --appstream && flatpak update -y
  1. Now try the operating system upgrade again and go to Endless OS 3.7.6
