Just upgrade to 14.04 lts ubuntu server and ...... logitech media server was not working...... stumbled back into these forums and, again, Ian had the answer:
"NOTE: At the time of writing the released version of Logitech MediaServer does not work on Trusty Tahr 14.04LTS so use the "stable beta" instead. So please use: deb http://debian.slimdevices.com testing main"
I do not know how you keep up with all this.
Anyway, purged old mediaserver, installed the new stable beta as you suggest/instruct and now everything seems fine again..... at least I can get access to the Logitech Media Server Web interface again (it is busy rescanning my music library);
Meantime, I saw you recommended to someone that they do this:
<code>
$sudo apt-get install update-manager-core
</code>
before do-release-upgrade and after apt-get update (with sudos, of course)
I did not have this step - things seemed to go OK anyway; can you tell me what this does? Thanks again for all your help.
