I installed flatpak via the command lines on their website and then proceeded to add the remote repository as instructed, but when I try to install something it says to specify a remote. I was trying to install inkscape from flathub.
Here are the command lines I used:
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
I also tried without sudo
To download the ref file:
wget https://www.flathub.org/apps/details/org.videolan.VLC
To install:
flatpak install org.videolan.VLC
Error Message:
error: REMOTE and REF must be specified
