    “Ubuntu has developed its new version “Xenial Xerus” that hung my
    system, following in the footsteps of Microsoft in the “touch”
    evolution, and so it has broken the wonder of Linux, in its memory
    savings, and their accurate and economical hardware’s management…

    Competing with Microsoft is the worst thing that could do Canonical, because it is losing loyal fans like myself!

    Since
    only there will be updates to the “Xenial Xerus” (Ubuntu 16.04 LTS),
    and will be no more updates “Wily Werewolf” (Ubuntu 15.10), I will
    continue working without updating, or I’ll work instead with Linux Mint
    or Linux Mate, or more better, directly with Debian…”

    I am sorry to read this and i wish you could get out of trouble. But, it is know that we should wait 1 or 2 month after a new release get out before installing as primary desktop, time for it to be stable enough except if you know how to get out of bad things.

    At any time you can probably make back up of personal data and then go back to stable version such as 14.04.4 ans then wait for Xerus being stable. I personally never upgrade from a version to a version (what ever the distro i used Fedora, Ubuntu, Opensuse) instead i prefer fresh install after good back up …

    Anyway, after last updates i feel Xerus wich is install alone on 3 computers, more and more stable …

    hope you get out !
    By the way, Mint 18 is coming soon ūüėČ

    Why “Xenial Xerus” (Ubuntu 16.04 LTS) does not work properly and make Ram memory overflow, while “Wily Werewolf” (Ubuntu 15.10) work right?

    Xenial Xerus is spending to start more that twice amount of Ram memory than Wily Werewolf!

    I want to work again with Wily Werewolf!

    Does anybody know how to uninstall Xenial Xerus to get back again Wily Werewolf?

    Now, I have erased my HD’s computer at all! And I am installing now in a hard work again from the beginning, the Wily Werewolf’s Linux (Ubuntu 15.10) and all my programs and utilities!

    I will not install never anymore Xenial Xerus!

    Only now, after almost 48 hours followed by hard work, I’m starting to work with my computer; I still have another 24 or 48 hours of hard work!

    I stepped back to the previous version, as I could not uninstall the new update, completely formatting the hard drive and reinstalling entirely the penultimate version “Wily Werewolf” (Ubuntu 15.10 LTS), which is what I’m still installing with his applications and programs…

    This is the worst mistake of Mark Shuttleworth, as president and founder of Canonical Ltd, because he is demolishing his own creation…!
