I tried to install the GNOME Web browser from Software>GNOME Web>Install
I received the error:
Detailed errors from the package manager follow:
Not found org.gnome.Platform/x86_64/3.26
Not sure how to resolve this.
This sounds like a Flatpak instead of a regular package, maybe @zlatan-todoric would have some trick for it, otherwise it might be best to file it as a bug report in tracker.pureos.net …
It does sound like flatpak thingy. Can you paste me the output of this command:
and also if there is some source in /etc/apt/sources.list.d/ dir.
Simple solution to this should anyway be to run this command in terminal:
sudo apt install epiphany-browser
