I had a snap version of Inkscape in Ubuntu 18.04.
I did not find anyway to give permissions to the /media folder.
This is a crippling limitation for the use of this snap, as I have a double-boot system and many files on my Windows partition which is under /media…
I had to unsinstall and reinstall from another source.
I used the flatpak version, and it did not have this limitation.
I will have to avoir snap installs as much as possibe until there is an easy way to release such permissions
