VSCodium can't save file if it needs root privileges (Linux Flatpak)

If I open a text file that needs root privileges to modify, I get this error:

Failed to save 'this_file': Insufficient permissions. Select 'Retry as Sudo' to retry as superuser.

That's fine, that's expected.

But when I click on "Retry as Sudo", I get this error:

Failed to save 'this_file': Unable to find pkexec or kdesudo.

This happens though pkexec is installed on my machine, at /usr/bin/pkexec; and I granted VSCodium access to it through Flatseal. How do I fix this?

lol yeah

You are going to want to run something like flatpak list to see what flatpak calls the app. It will be a com.something.codium or similar.

Then you can open the file by running it as sudo flatpak run flat.pak.app and then find your file. You should be able to edit and save.

It is a bit involved, but usually people will do this via cli text editor and just say sudo editor file.txt. We need the extra steps here due to gui app.

Running as root is a forceful workaround, not the solution to my problem. I want to open this lock, not break it.

::: spoiler I don't want to run as root because...

It's bad for security. Think of running sudoedit vs sudo nano or sudo vim. If you run the editor as root directly, you can access the shell as root. This is a feature, not a bug! But if you run sudoedit, it stays at low privilege level until it actually saves the file.
The "Retry as Sudo" feature exists. If it's there, why not use it instead of circumventing it?
At this point, editing the file is irrelevant. This is not an XY problem. I want to stop getting the second error. :::

The "Retry as Sudo" dialog is supposed to appear, and when I click on the button, I am supposed to get a password prompt. That's what happens in the Apt version; that's what happens in the Snap version; and in the NixPKG version, they had the same problem, but they fixed it.

How do I fix it in my flatpak version?

Hmmm I am not sure. Might be worth asking in one of the mainline linux communities. At a minimum they might be able to point to a more active community instance for asking questions. As it is, this is not really a VSC issue per say.

I kept fixing and then kept having new problems with vscdoium in flatpak, either have to give it all permission or give up maybe. As I was using it there would be new problems every once in a while, and different extensions introduced new issues too lol

I gave up and just installed it through AUR.

Even though it's vscodium and not vscode you can run it with firejail --net=none /sbin/vscodium and it won't have access to the internet

I think you need a polkit authentication agent installed and running to prompt you for your password.

Alternatively you can sudo codium path/to/file (assuming you have aliased codium to use your flatpak)
