Using Chrome flatpak in Clear Linux, I get this error message when attempting to install any of them Chrome apps from within Chrome (such as Twitter, Flathub Discourse etc.):
These apps, I take it, are called PWAs, which appears to stand for “progressive web apps.” So I open up Flatseal, give Chrome the required access to them folders, and still keep getting this error when attempting to install PWAs.
How do I fix this please?
I use an override on the command line:
flatpak override --user --filesystem=~/.local/share/applications --filesystem=~/.local/share/icons com.microsoft.Edge
(Adjust for your preferred browser)
Thanks. Have you tried Flatseal as well? Would you mind giving it a try, see if it works for you? After all, this is a paradigm use for Flatseal, and it is somewhat disconcerting to see that it does not work.
Report the issue to the maintainer of the Flatpak you’re using
For Chrome Flatpak that looks like this one Issues · flathub/com.google.Chrome · GitHub
Yeah it should look something like this:
You’ve caught me on a busy day (and in the middle of a new computer setup!) so I don’t have the time to do it but if we someone each browser and took a picture of what it looks like in Flatseal and posted it here alongside the CLI instructions it would at least be a signpost for people to get working even though the solution is ugly. 
Yep, that’s precisely what I did in Flatseal. Doesn’t work.
