Raspberry Pi B + Raspbian Stretch + Mono 5.14 -> crash on start-up

[Z_God 0]

I'm new to Emby and am trying to install it on my Pi. When I try to run it, it crashes however.

 

Any idea what is going on and how I could solve this? Here is the output:

Hi, I'm afraid we haven't tested mono 5.14 yet. 5.12 is as high as we've gone.

 

What model RPI is this? Because if the architecture is armhf then you should just use our debian package instead:

 

https://emby.media/linux-server.html

[Z_God 0]

Thanks for the reply!

 

It's a model B. I tried the package initially but it seemed to use the dotnet runtime from Microsoft which doesn't support this CPU yet.

 

Raspbian has Mono 4.6 in its repositories, but as that seemed to old I added the Mono Project repository and updated everything to the version from there. Is there a way to get version 5.12 instead?

[Luke 42078]

What cpu is it? What happened when you tried the package on our website?

[Z_God 0]

Here's more info on the CPU:

$ cat /proc/cpuinfo
processor    : 0
model name    : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS    : 697.95
Features    : half thumb fastmult vfp edsp java tls
CPU implementer    : 0x41
CPU architecture: 7
CPU variant    : 0x0
CPU part    : 0xb76
CPU revision    : 7

Hardware    : BCM2835
Revision    : 000e
Serial        : 00000000dbc3e38c
 

With the package it segfaulted with an invalid instruction if I remember correctly. I think it's this issue: https://github.com/dotnet/coreclr/issues/10605

[Luke 42078]

What process did you use to install the server?

[Z_God 0]

With the package, I had just used 'dpkg -i' on it.

 

For the Mono build, I unzipped embyserver-mono_3.5.2.0.zip from the releases page on Github. I had to create a symlink for libsqlite3.so because it's called libsqlite3.so.0 on my system. (I put that symlink in a subdirectory lib. That's why I added the LD_LIBRARY_PATH.) Then I ran mono as you see in my output.

[Luke 42078]

Ok, sadly, the best i can say right now would be to figure out how to get an older version of mono onto your system, and I don't have the answers on how to do that.

If there is enough user demand then we'll consider an armv6 mono package. We're starting to create new mono packages now to fill in support for devices that .net core can't reach. Thanks.

[Z_God 0]

Thanks! I'd be happy to test anything that comes out of that effort! I'll see if I can find an older Mono version for now. Do you know what kind of changes would be needed to make Emby run on a newer Mono version? Would that be a matter of compiling it for that version or are more changes needed?

[Luke 42078]

I really haven't looked at 5.14 yet so it's hard to say.  You could also try the netframework zip instead. Going forward that's going to replace the mono zip. The outcome might just be the same though.

[Z_God 0]

I just tried that package, but it gives me this output:

$ mono ./EmbyServer.exe

I searched a bit and found a package with this library, but it has version 4.0.0.0 instead of 4.0.2.0:

$ dpkg -L libmono-system-runtime-interopservices-runtimeinformation4.0-cil
/.

Maybe it would be possible to make it less strict regarding the version of that library?

[Luke 42078]

Try the one on the beta server.

[Z_God 0]

I tried both the mono and netframework packages for 3.6.0.2-beta but they seem to be have the same as their 3.5.2 variants. Or you meant something else with 'the beta server'? I wasn't completely sure.

[Z_God 0]

Let me know if there's already any update on this. I'll be glad to try a newer version again!

[Luke 42078]

Yes you could try the latest beta server, thanks.

[Z_God 0]

I just tried the latest version of the beta server, embyserver-netframework_3.6.0.65.zip.

 

It still has the 4.0.0.0 VS 4.0.2.0 problem.

[Luke 42078]

Can you please attach the emby server log? thanks.

If you wish to pin mono to a certain version you will want to use a source formatted something like this:

deb http://download.mono-project.com/repo/debian wheezy/snapshots/4.8.1 main

But modify the end part there to proper version. I think mono also has instructions on doing this.
