UHD volume key not found 1.15.3

[nemeth27]

Ever since I updated to 1.15.3 I have not been able to open UHD Blu Rays. I keep getting “The volume key is unknown for this disc - video can’t be decrypted.” I’m even getting in on MY UHD blu rays I ripped on previous version.

Drive is a LG UH12NS40

Any ideas?

Does your log mention not being able to contact the web server to get the latest hash key list?

It looks like it's loading.

Two different kinds of "hash keys"... One has the information for decoding UHD disks, the other is an on-disk table of information to verify that the contents were read correctly.

In your case, the log is missing a message about "Downloading latest HK to ...", which would normally happen whenever a 4K UHD disk is loaded, unless you've disabled contacting the web server for updates. If it is enabled but fails, you get two messages, the second one being "Automatic HK downloading is disabled or failed."

The HK file that is downloaded has the latest decryption keys, and is updated quite often. Without it, you get the "volume key is unknown" message.

Thank you for the info.

So, I have Enable Internet Access checked off in Online updates. Do you have any idea what else would prevent it from downloading the file?

I know that at the same time I did the update I also purchased a registration key. Could the key have an issue?

[dcoke22]

Enable Internet Access needs to be turned on for it to be able to attempt to download the necessary decryption keys.

Maybe it is a trick of language where when you say 'checked off' you really mean turned on. But if it is turned off, please turn it on.

This is a soft bug in MakeMKV 1.15.3 on Linux - it fails to find libcurl, specifically even if you have the common libcurl-gnutls installed then MakeMKV won't find it. Next version fixes this. Two possible workarounds:

1. sudo apt-install libcurl4

or

2. MMCURL_PATH=/path/to/your/libcurl-gnutls.4.so

I am having this same issue


Trying to do #1 - it's already installed.

Where does #2 go?

Or should I just wait for the next version? ETA?

[Woodstock]

It depends on how "permanent" you want the setting of the shell variable to be. If you simply type it at the command line before executing MakeMKV, it will disappear when that shell is closed. Or, you could add it to /etc/bashrc to set it for all users, or in ~/.bash_profile if you only want it for your normal user.

[Metallikahn]

I'm having this exact same issue. I'm running this from a an unRAID server Docker, made by Jlesage. Pretend I'm pretty much illiterate when it comes to linux commands and what not (Because I'm pretty hopeless, to tell the truth... I like my nice easy GUI's lol) How would I go about fixing this? OR How would one go about rolling it back to the previous version?

Still doing this on 1.15.4

Latest image from jlesage has libcurl installed and now works!

[jefftr66]

Ok spoke too soon. No more key errors but the main movie file fails - tried twice...

This is the end of the error msg - much more in pastebin:

I should also say:

I was able to rip all the other, smaller files (like commentary from producers, director, etc.) Only the main movie file fails.

Seems like if it was a disk or drive problem no files would be able to ripped

That error indicates the drive couldn't read some of the bits.
