Hi,
I upgraded from mediacenter30, and 34 don't start. It's strange, but mediacenter 30 is still installed and working. When I first started up 34, I was able to enter my license, but since then nothing works. If I try via the terminal with mediacenter34, I get no message. Same with
mediacenter34 /BuiltInBrowser
Thanks for support

[JimH]

Install 34.0.24

Reboot

Then do mediacenter34 /BuiltInBrowser

[kona68]

Thanks, it's OK now. 

But I don't understand why it failed before with BryanC's method:
curl -O https://git.bryanroessler.com/bryan/installJRMC/raw/master/installJRMC &&
chmod +x ./installJRMC &&
./installJRMC

[BryanC]

They are unrelated commands, installJRMC is for installing MC and mediacenter34 /BuiltInBrowser is to actually run it. The reason it failed to run initially is because of chromium browser issues that /BuiltinBrowser works around. After running that command once, MC should should launch fine moving forward so you can start it from your application launcher/start menu normally.

My effort to get JRiver back and working on some Linux on some computer I have may just have to end unsuccessfully.

With just a 32 license, my current main computer (not a Mac)  was originally on Fedora KDE but I could not get JRiver to run. So switched to Kubuntu, been working fine, through MediaCenter 33, but now that it is on Plucky and JRiver 34, as I have noted, stops every few tracks making JRiver unusable except as server. No such issues before.

Was advised I try another OS, so since I can't wipe my main machine, I installed Mint on an older spare machine I have. Runs great, but turns out the sound is a mess and it's a well known issue with messed up audio over HDMI with recent Ubuntu and Debian and derivatives. nothing to do with JRiver. None of the solutions I found online (revert to pulseaudio; disable WiFi) fix it.

Can't even get Ubuntu or any flavor to boot on that device, though Mint worked.

Tried Debian (Bookworm) as that is the one and only officially supported linux for JRiver, but yeah it has same messed up audio over HDMI noted above.

So back to Fedora, which is great with me. Installed the standard Workstation (GNOME) which is running wonderfully on my spare old machine. Except, yup, JRiver will not run. Tried the
 mediacenter34 /BuiltInBrowser
but no,. Actually result is similar to what i first saw on my main machine trying to run earlier MediaCenter on Fedora KDE. Sorta looks like it's gonna run once or so, then nothing,. Nothing. Nothing. Did get a segmentation fault when running mediacenter34 /BuiltInBrowser.

Any non-Fedora, non-Debian/Ubuntu derivatives that JRiver runs under? OpenSuse work nowadays? Manjaro?

Or do I need to give up on my music library until I buy myself a new Mac one day, some day?

34.0.24?

Using installJRMC?

[JimH]

Are you running MC from the machine itself?  Not a virtual desktop?

MC requires X11.  You could read about that in other threads on the Linux boards.

If you use installJRMC on Debian or Ubuntu, it should work, probably on other distros.

Bookworm is new to us.  We've learned a little in the last couple of weeks.

I'm hoping that Bob from JRiver will be able to give you better guidance.

Segfaults are sometimes hard to reproduce and hunt down the cause of unfortunately. If you're getting segfaults try what I posted here to try to get more info about it to help Bob find the issue.

Whenever you have issues segfaulting on start in a setup that worked previously (same OS, hardware, etc) you might have corrupted settings files.
That can come from interrupting a startup by killing the process and other things.

You can try removing the Settings file(s). You will lose you settings and library. Hopefully you have a backup.
First try just removing the user settings.

rm ~/.jriver/Media\ Center\ 34/Settings/User\ Settings.ini
and restart MC.
If it still segfaults remove both the one above and the Machine Settings.
rm ~/.jriver/Media\ Center\ 34/Settings/Machine\ Settings.ini

If MC still won't start you have other issues.

Thanks for replies. Okay, here to recap previous posts.

No virtual machines at all.

Main machine= convertible PC that shipped with Windows 11. Needs to run KDE for best function of hardware.
Was running KDE Fedora, used installJRMC to install MediaCenter 32 but install was a fail. Kinda started a couple times, then useless.
Only because I need to use JRiver, I wiped out my lovely Fedora KDE install and from scratch did a  Kubuntu install. It is a hassle getting dualboot all setup on that but I managed a second time, now with Ubuntu flavor, I keep Windows just because, well, I paid for it as part of the machine's cost and one day may need access to some commercial software or something Linux can't run. Since I was now on an Ubuntu, I could instead of installJRMC which has never worked for me, use the "add repo manually" method. Worked great!

Ran 32 then 33 , no real issues beyond usual.

Plucky upgrade and paid upgrade to JRiver 34. Asked here for commands to install from repo manually; no answer so I ran installJRMC. In 34, player immediately started freezing between tracks ever couple or few songs. So, it was now unusable. Advice I got here was to install a different OS.

I can't wipe my main machine, so decided to use it to host library.

So...

secondary machine = old Mac mini as library client / guest.

No Ubuntu flavor will boot off USB; known issue (nothing to do with JRiver).

Went with Mint, latest, w/ Cinnamon.

Installed great. Ran installJRMC. MC34 opens fine. Okay, grand. Except... HDMI audio is all messed up; turns out it is known issue on assorted machines, not just Macs, with Debian and Ubuntu and derivatives since switch to PipeWire. Nothing to do with MediaCenter. Solutions suggested online include reverting to PulseAudio and/or disabling WiFi. Did both, but those maneuvers brought no help.

So, Mint sadly is a no. Tried Debian, being all y'all's offically supported Linux, and yup same bad HDMI audio. Kinda amazing that users have reported this for a while, and seems Ubuntu nor Mint nor even Debian have solved.

So, on to Fedora here on secondary ol' machine. Fedora installer is very nice nowadays, by the way. Installed Gnome. Clean install. Did nothing but install OS and run all updates, then install JRiver via installJRMC.

No luck launching. Ran terminal command
mediacenter34 /BuiltInBrowser
Got a couple half launches and freezes. Wiped system to try some other OS, but then read replies here, so....


Another clean install of Fedora. Did nothing but install and run all updates, then install JRiver via installJRMC.

this time I immediately rebooted.

then ran mediacenter34 /BuiltInBrowser.

App launched. I told it to import nothing. Closed it. Launched it normal way, Yay.

Then restored my library, just settings not files (because I have some fields I have added over years, etc, that I need, but will be logging in to remote main library).

App said it would close and restart but never closed. This happens on Mac too sometimes when restoring. Guessing this is one of those things that works better in Windows, dunno. But anyhow this latest library restores just fine on main machine, and also on macOS install on other partition here (which I can't use as my main OS since it is out of support, no security updates, etc, hence Linux). So the library backup is fine. Same library also restored successfully when I was running Mint.

Eventually I restart. App launches and gives me database notice and then nothing.

Reboot again.

run terminal command

rm ~/.jriver/Media\ Center\ 34/Settings/User\ Settings.ini

no luck

then run
rm ~/.jriver/Media\ Center\ 34/Settings/Machine\ Settings.ini
 no luck

and also again

rm ~/.jriver/Media\ Center\ 34/Settings/User\ Settings.ini
followed by
rm ~/.jriver/Media\ Center\ 34/Settings/Machine\ Settings.ini

Nope. Will not launch.

Again, this is clean install of Fedora in perfect working order.

So, shame about Debian and Ubuntu flavors outputting bad audio in recent versions or I woulda stayed on Mint, where JRiver seemed promising. But Fedora is not working.

[BryanC]

I have no problems with MC on Fedora 42. After installation are you restoring a library backup and/or importing the same media?

Since your errors seem tangentially related to display issues, what GPU are you using and which driver?

Are there any errors in the journal or dmesg that may provide more insight?
