AppStream Report for PureOS - Issues for psi-plus in landing/main

Errors

icon-not-found
The icon 'psi-plus' was not found in the archive. This issue can have multiple reasons:
- The icon is not present in the archive.
- The icon is in a wrong directory.
- The icon is not available in a suitable size (at least 64x64px)
- On Debian and Ubuntu, the icon is a symlink. The generator cannot read symlinks on these distributions - make the icon a real file.
To make the icon easier to find, place it in /usr/share/icons/hicolor/<size>/apps and ensure the Icon= value of the .desktop file is set correctly.
