ChromeOS | Linux Development Environment | fix “no remote refs found similar to flathub” error

• Open the Linux Development Environment menu
• From within the menu select Penguin to open a Linux Terminal windows
• At the command prompt type:

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

• You should find that your Flatpak commands will now work. However, in one instance we did get the following error message, “Unable to load summary from remote flathub: GPG verification“.
• So to fix this problem we basically going to confirm that we have the right link to the Flatpak repository, and that we are using the correct GPG key.

Note: Gnu Privacy Guard or GPG is an open source encryption technology.

• From the command prompt type:

sudo flatpak remote-delete flathub

• Now type the following to point to the correct flatpak repositories and refresh the GPG key:

sudo flatpak remote-add flathub https://flathub.org/repo/flathub.flatpakrepo

• You should now once again be able to install packages using Flathub commands.
