This only happens with the ‘easy install’. However it happens on Ubuntu and I’ve just tried it on an arm device and same thing.
I thought I should post it here so I have a place to say how I fixed it, or if I don’t Roon support might step in and fix it since it’s now happened a couple of times on a couple of different linux distros.
In the VI editor, line 17 is of course blank, that’s useful.
Your title mentions line 12 but you mention 17 in your second post. I’m assuming that 12 is correct…
PACKAGE_NAME_LOWER=${PACKAGE_NAME,}
This is correct syntax to take the value of $PACKAGE_NAME (RoonServer) and convert it to lower case.
Did you download the install script on a different machine and then move it to the linux box or did you grab it directly with the curl command?
Hey, I used wget directly on the machine. Then basically +x etc.
So, I installed curl, just to humour the idea that there’s something specific to curl, the ran through exactly as per web site as below. In this particular case I’m on a Raspbery Pi BTW. You’ll note the very odd error below which interestingly I also remember getting on Ubuntu with it some time ago.

Bah.
I realise I ran the whole thing on the incorrect x86 binary just now. However, the same applies to the ARM binary, though to humour myself I’m doing it all again now, will report if there is any difference.
Yep exactly same.

Also, I’m using Tiny Core Linux in this case, which does appear to be set to use /bin/sh.
On the same machine, download manual version:
~/RoonBridge$ ./check.sh

Running
And now it all works. Not sure what all the HEX code is, nor what Fast TLS is, but it’s working when I go into roon, songs play well, it’s identified as a Roon device and say’s it lossless etc.
Further investigation indicates the error on the manual version is a problem with Mono, which is bundled with Roon. It doesn’t seem to cause any issues, but would be fixed upstream at some point. That doesn’t explain the ‘easy’ install script though, which is clearly not easy at all.
I ran into this a while back and I think that it has to do with different sh packages installed on different distros.
IIRC using the full path to sh worked.
sudo /bin/sh roon_installer.sh
@amp Hi Andrew, I’m getting this same message on the Linux easy install script. I am trying to load Roon onto a Netgear ReadyNAS Pioneer Pro.
I tried your solution
sudo /bin/sh roonserver-installer-linuxx64.sh but it yields the same error. Bash and SH are both on the system. Any Ideas?
If tr command is available you could try to replace that line with:
PACKAGE_NAME_LOWER=`echo "$PACKAGE_NAME" | tr "[:upper:]" "[:lower:]"`
${PACKAGE_NAME,} will only work with bash >= 4.0.
Thanks Christopher. I’m sure the bash on the unit is older than 4.0. So, used your line and it worked to resolve the issue. 
Just changed it to use tr always. That’s probably a safer bet than bash>4.0.
