Today, I tried to rip a new blu-ray disc on my Linux computer and I got a weird error. This is what I got:

Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc

As a hunch, I went and downloaded an evaluation copy of MAKEMKV on my windows computer and it worked successfully.

Any idea why?

Mayhaps your Linux version doesn't have permission to download the key database. Happens to a lot of people, many of whom don't know that their DNS is blocked at the ISP level.

Perhaps.

I fixed it by going back to the previous version of 1.17.4
I even used a deb package instead of flatpak. I wonder if that had anything do with it as well.

I am also seeing the same issue on 1.17.5

How did you go back to 1.17.4? I am suspecting I am having a similar issue but I do not have a windows machine to test with.
I also can not find the old version install guide on the forums or anywhere to download it. I used a flatpak when installing initially.

FWIW I am successfully using MakeMKV 1.17.5 with VLC on Fedora Linux to play BluRays. Are your Linux and Windows boxes using identical KEYDB.cfg files? Or does your Linux user ID not have the correct permissions to open the BluRay drive's device nodes (e.g. /dev/sg0, /dev/sr0)? E.g. The nodes need to be available for both reading and writing, and so my own user ID belongs to both the cdrom and disk groups.
