I have Linux Mint 21.3, at the moment.

I can't upgrade.
 
It installs but does not start.

Try running mediacenter34 /BuiltInBrowser from the Terminal. You might be encountering the known issue with the Chromium-based browser in MC34 right now. If it starts using the /BuiltInBrowser switch, that's the reason why.

Also I hate to say it but Linux Mint 21.3 would be considered old at this point, as I don't think it gets anymore updates. Upgrading to 22 would be my personal recommendation (or switching to a different distro is a potential option as well).

I can't update or switch system.
The reason of the problem seems to be the glibc 2.36 (see attachment), in that a case a "simple" .appimage version will probably solve my problem (and that of who knows how many other users). Thank

[Awesome Donkey]

Oh, yeah, unfortunately Linux Mint 21.3 is too old then. It's possible you could use installJRMC with the --compat switch but it may not work if glibc is too old.

Just curious, why isn't upgrading to Linux Mint 22 an option? It should be a pretty straightforward process.

According to Wikipedia Mint was released in January 2024 and is supported until April 2027. That isn't old.

As it happens, I'm using Mint 21.3 on a laptop and MC 34 won't run. I've tried upgrading to Mint 22 and it won't (at least not if you don't have an in depth knowledge of Linux arcana). That leaves the option of a clean install which means that all the programs that are currently installed will have to be reinstalled and settings reconfigured. That's a major pain just to enable one program to run. (I have not had any issues with incompatibility with any other Linux program that I use, even stuff running under Wine.)

I have to say it makes Windows look good! I would hazard a guess that the Windows version will run happily on much older versions of Windows.

That's not really the issue (and it's good it still gets updates for two more years). JRiver only officially supports Debian and it was announced a month ago that MC34 would be moving to Debian Bookworm as the base/build system. The issue here is Linux Mint 21.3 (and likely Ubuntu 22.04 LTS too) are older than Debian Bookworm and ship with libraries and dependencies, specifically glibc, which are too old for MC34 to run correctly on it. The distro you're using either has to match or exceed the version of the library/dependency (glibc in this case) for MC34 to function correctly. Yes, Bob and the team does sometimes address issues with getting Media Center running on non-Debian distros, it doesn't change the fact that a) they only officially support Debian and b) the distro you're using has to match or exceed the libraries/dependencies needed for Media Center to function correctly, otherwise it's too old and likely won't work. This is no different than macOS when new MC versions have to target a new minimum version of macOS, though in Linux it'll happen faster. System requirements change as time passes, the minimum version of an OS changes a specific version of an app runs on will change too. That's how it always has been with all OSes.

And as I said, Linux in general is the most unforgiving platform when it comes to maintaining backwards compatibility with newer apps and older distros that have older libraries and dependencies they ship with (especially glibc) becoming too old to run certain apps. Windows is the best platform when it comes to backwards compatibility, then macOS (though it's not great either honestly) and then Linux.

XY, this is your issue. You need to figure this out and/or switch to a distribution with better in-place upgrades.

[Awesome Donkey]

That leaves the option of a clean install which means that all the programs that are currently installed will have to be reinstalled and settings reconfigured.

Well, depending on the app you can backup most settings, especially those in the hidden .config folder in your Home directory. Likely won't work for web browsers unless the hostname and everything is exactly the same (though for Firefox you can copy and paste the entire .mozilla folder in the Home directory and if it's Chrome/Edge/Opera/Vivaldi/etc. using the web browser's sync feature probably is the best workaround), but for other apps it may work. For MC itself do a library backup (or just backup the entire hidden .jriver folder in the Home directory). And put all that in a location like a USB stick or something not affected by the OS reinstall. Then after the OS reinstall and it boots, put the USB stick in and start copying stuff back over.

[sergioz]

Solved by me.

Procedure (simple): (not do it if you don't want to risk breaking something; in theory some of the new function of MC34 may not work)

1 - open with nemo /usr/lib/jriver
2 - click with RMB and choose "open as an administrator" and log in
3 - there you will find Media Center 33 (if you buy it last year) and Media Center 34
4 - open Media Center 33 and copy the file libJRReader.so
5 - open Media Center 34, rename the new version of the file libJRReader.so in libJRReader.so.OLD
6 - click an empty space with RMB and choose "paste".
Done. You can start up MC34

[Awesome Donkey]

That's... definitely not a recommended solution to the issue, and will likely cause more problems than it solves. Ideally you should probably just stick with Media Center 33 or just update/reinstall to Linux Mint 22 (or switch to Debian Bookworm, the only distro JRiver officially supports) if you want to run Media Center 34 without resorting to less than ideal (and not to mention unsupported) workarounds.

[bat9]

Sergioz LOL.... that indeed may perhaps lead to other issues, but how in the world did you find that specific way of resolving your particular issue???

[sergioz]

bat9: simple, just read the screenshot of the terminal I posted above 

Oh... and no smoke exit from the PC neither 

Developers think too much at y o u r s business and less to other thing: for example is almost from 2017 that Media Center opens directly on the secondary screen (a TV in my case): never fixed. I use it for audio files, all the fuss about TV functions doesn't interest me at all, I'll never use them. Next version I'll think twice before spend my money for people that want to decide what SO I must install in my pc.

Sergioz,
Would you mind stopping being an ass? 

This is your first and last warning.

Thanks.
