I am using Ubuntu 22.10 as administrator.

I mounted an image file (raw, ext4) as a disk but however I had changed the "Permissions" of the disk (to "create and delete files", etc), it was read-only.

How to change it so that it can be writable?

Thanks.

  • need more detail. How did you mount it? fstab options? Did you use chmod or chattr? – user10489 Feb 21 '23 at 05:58
  • It was mountable after fsck and e2fsck. chmod did not work. – wenyuan Feb 22 '23 at 07:03
  • fsck calls e2fsck, it's silly to run both. "chmod did not work" is meaningless. Supply a real error and include it in your question. You say you "changed permissions" -- how did you do that? These details need to be in your question. – user10489 Feb 23 '23 at 01:55
  • Right-click on the file / disk -> Select "Properties" -> Click on "Permissions“. Thanks for being constructive. The purpose of this thread is to find the solution to solve the issue. – wenyuan Feb 23 '23 at 04:53
  • You should add that to your question. Adding output form ls -l on the item you right clicked on might help too. You can probably just repeat what you did and add the permission back. – user10489 Feb 23 '23 at 12:23
