How to make a read-only disk writable?

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?

It was mountable after fsck and e2fsck. chmod did not work.

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.

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.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
