I'm ready to migrate to Ubuntu but when I went to the download section I read "The latest version of the Ubuntu operating system for desktop PCs and laptops, Ubuntu 15.04 comes with nine months of security and maintenance updates" What that means? Is this a trial version? why only 9 months?
Like I said in the beginning of my post I'm ready to migrate, but not if it's only for 9 months.
I apologise in advance if this is a stupid question or it's obvious for you, but I don't know anything about ubuntu, so I'd be glad if somebody could clarify that for me.
