    This looks really simple to follow but being a little bit cautious (and not massively knowledgeable about Linux in general), will an upgrade work for me as I’m using LM 17.3 dual booting with Windows 10, will Grub etc… be ok with this?

    Also, I’m using the KDE desktop, will the upgrade automatically give me the 18 KDE desktop?

    sorry if questions are a bit Donkey!

    thanks in advance

      It will work, however, make sure you perform a backup before upgrading.

        Thanks Aaron for the reassurance, already backed up to my NAS using “REDO Recovery and Backup“, will give it a go later and report back, got 2 dual boot pcs and 1 USB to do so should be interesting :-)

          that went well then, got as far as “mintupgrade check“, I get “ERROR: Your edition of Linux Mint is ‘KDE’. It cannot be upgraded to Linux Mint 18 ‘Sarah’ – I guess that’s the end of that then?

          • Aaron Kili says:


            This guide is intended for Linux Mint 18 ‘Sarah’ – Cinnamon(default desktop environment). The KDE edition isn’t upgradable (Linux Mint 18 KDE uses a new and different desktop called Plasma).

            Try to fresh install Linux Mint 18 KDE.

            thanks Aaron, I like Linux Mint when it’s all up and running but cannot believe how hard even the simplest task seems to be!

            Apparently, even if you get Linux Mint 18 on a bootable USB, you’re still restricted to only 4GB persistence, why/who on earth thinks this stuff up? think it’s time to look for a far less restrictive distro, thanks anyway

    Thank you so much. Much easier to follow than the official instructions.

    Me too. Perfect tutorial/process.

    Dell Mini 9 still chugging a long. (Like molasses in winter, but still working fine)

    Did upgrade 17/3 to 18/1 without problems. Thanks for easy to follow instruction / I as an 77+ years old was able to install upgrade,
