Hello! I use Bazzite Linux with KDE, and I'm having some issues with duplex printing on my system.

I have a Brother HL-L2300D, and I've already installed the drivers for it. Brother provides an install script for their driver on their website, but because my system is rpm-ostree based and immutable, I would get rpm-ostree errors and the installation would fail.

I found a Reddit post yesterday that suggested running sudo rpm-ostree install printer-driver-brlaser, which worked and I was able to connect to the printer and configure everything as needed.

However, when I try to print on both sides of the page, the back side of the page prints upside-down. I've tried changing the setting for which edge to flip when printing (portrait/landscape), and it doesn't seem to change anything. I printed the same document on a Windows machine on this printer, and it went through just fine, so I've isolated the problem down to the CUPS server that my machine is running.

If there's any more information I can provide, please let me know. I've tried the troubleshooting steps I know and have reached the limit of my knowledge.

Creating importer: Failed to invoke skopeo proxy method OpenImage: remote error: cryptographic signature verification failed: invalid signature when validating ASN.1 encoded signature ___

I was banging my head against my keyboard for an hour thinking that I broke my system until I saw this.

Edit: I found the solution! All I had to do was add the uid with my username, then I also had to add "forceuid" for it to actually go through. My fstab entry now looks like:

//192.168.1.21/Media-Library /mnt/Home-NAS/Media-Library cifs user=Jellyfin,password=password,uid=my_uid,forceuid,iocharset=utf8 0 0

Thank you @lemmyreader@lemmy.ml for posting the solution from Stack Exchange!

Hello! I have an Ubuntu server with a NAS mounted using cifs-utils, and I've created an entry in fstab for the share to be mounted at boot.

My fstab entry looks like this:

//192.168.1.21/Media-Library /mnt/Home-NAS/Media-Library cifs user=Jellyfin,password=password,iocharset=utf8 0 0

(The password is not actually "password" of course)

However, while I'm able to access the share perfectly fine, and even have a Jellyfin server reading from it, I cannot write files to the share without using sudo. I have some applications that manage metadata for music, and they're not able to change or add files in any way.

I am however able to access the share from my Fedora machine just fine with the same credentials, since I use KDE, I just added them to the default "Windows Share Credentials" setting. I don't have the issue where I have to use sudo to modify files, so I know it's just an issue with the share mounted to the server and not permission issues on the NAS itself.

What am I doing wrong?
