From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

No permissions - Did I bonk my LUKS encryption? (lemmy.ml)

Hello Linux Helpdesk. ;)

I use Fedora (currently 40), and have done for a while.

I always LUKS+Ext4 encrypt my local drive and decided to do the same to my external hard drive.

Last week I reinstalled Fedora 40 from a Bootable USB, but when I tried to access my files om my external drive it now gives me the error

You do not have permission to view the content of "Files".

I've read online it's due to me no longer being the "Owner" of the drive I was in my previous install of Fedora and now I'm a different user and apparently no users a part from Owner have any permissions on an EXT4+LUKS drive.

Is there any way to give myself permission to see the content again or did I bonk my backup? As a note, I DO have the correct Luks password, it shows me the name of the encrypted disk after decrypting, which is "Files"

Thank you in advance.

Edit: Thank you everybody, thanks to you I've been able to rescue my files. Y'all deserve a great day!

sudo chown -R youruser:youruser /path/to/mountpoint

Will make all the files in the path owned by you. Be careful if you have more complex permissions on there they will be lost.

This is where ACL permissions would help. He could give his new id ACL permissions to the files and that wouldn't mess with the current permissions.

From the root/beginning subdir: sudo setfacl -R -m u:{replace with your new id}:rwx .
