Recently I tried to install Logitech MediaServer on my Ubuntu 14.04 LTS “Trusty Tahr” server using the (official) setup steps described in the Squeezebox Wiki (see http://wiki.slimdevices.com/index.php/Debian_Package).
Immediately after starting the server the message
Logitech Media Server died. Restarting.
was written into the log file /var/log/squeezeboxserver/server.log.
After some research I found out that Logitech MediaServer 7.8 is needed to be compatible to the perl version that is included in Ubuntu 14.04 LTS and using the stable channel from http://debian.slimdevices.com will install version 7.7.x.
I was able to install version 7.8 using the installation package from http://downloads.slimdevices.com/:
wget http://downloads.slimdevices.com/LogitechMediaServer_v7.8.0/logitechmediaserver_7.8.0_all.deb sudo dpkg --install logitechmediaserver_7.8.0_all.deb
