how to force ubuntu disk image mounter to mount image files as writable?

i have an image and want to edit it a little for some configurations so that they will be available from first boot. but how? i opened the file but the mounted volumes are read-only. when i try sudo vi [file] under the mounted directories, and try to save the files, it says that the file in that partition is write-protected, so can't do anything. i tried remounting but doesn't work (even with root rights, it seems the mount points are write-protected from being remounted).

I stumbled upon this issue as well. The GUI did let me mount a new image as writable, but opening an already existing one always led to read only. This happens even if it is the same that I had just created, unmounted and opened again.

I had a look at the documentation for gnome-disk-image-mounter. I found this:

gnome-disk-image-mounter --writable file.img

If you run the above without specifying the file, a file picker will open instead.

For more information:

man gnome-disk-image-mounter

or

gnome-disk-image-mounter --help

Please remember that permissions still apply to the mounted folder. If it is owned by root and the write flag for the group or user you belong to is not set, then you will not have the permission to edit the mounted partition anyway. But that's an issue of permission rather than read-only mode.
