I have this error when i try to use chmod 777 -R to make a mounted harddrive writable and readable.
chmod changing permissions of <some file> Read-only file system
My fstab looks like this:
UUID=C08667CB8667C110 /media/wd_2tb_backup_photo_movies ntfs defaults 0 0
UUID=9fbfd421-7128-4eae-aa6d-fed5cb340e87 /media/pictures_raw_collection ext4 defaults 0 0
Both ntfs and ext4 i cant write to but mounts fine.
Using latest Ubuntu server 20.04 LTS
