Hi, I'm following this guide:
The build proccess stops with the following mesage:
Nota, viene selezionato "nfs-common" al posto di "nfs-client"
E: Unable to locate package language-support-writing-it
umount: /opt/ltsp/i386/proc: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
