I’ve seen this issue on the forum pertaining to external devices like media players and external drives, but not for the on-board file system. I installed PhotoGimp through Snap on Manjaro KDE Plasma, and I’m trying to customize the splash screen. The splash screen .png file is located in /var/lib/snapd/snap/141/config/splashes/. I can’t overwrite it using Gimp, terminal, Dolphin, or even the admin privileges in Nautilus. I’ve tried changing permissions and ownership, and each time it puts out an error like “chmod: changing permissions /var/blah/blah/blah/ Read-only file system” no matter whether I’m using sudo, su, or root in terminal, it wont make the change. I’m able to change permissions for every single folder in the path except for the /141/ folder, which seems to be the culprit. There seems to be no conceivable way to change permissions or take ownership of this folder. There is a lock bubble inside the folder icon. I’ve extensively searched the web for answers but everything I find talks about mounting external drives, which wouldn’t apply here because this is on my internal file system.
I understand the dangers of messing with the file system as root or admin, and I’m not changing any config files or anything, I simply want to overwrite the .png for the splash screen to one of my own creation which should not break anything. Given that Linux, Arch, and Manjaro all hail themselves as having complete freedom of customization, I’m surprised to find that I can’t do something that could otherwise be easily done on a Windows system like changing the permissions of a certain folder on the file system.
Any help here would be greatly appreciated. Thank you, in advance!
