    Got the RED X shield the other day and can’t update or upgrade. Have searched and tried may suggestions but will not update nor upgrade. Any suggestions? Thank you

    I reached the end of the upgrade from 17.3 to 18 but the upgrade ended on: Download complete and in download only mode.

    45-AIO-M870 ~ $ 

    Do I need to type anything else to finish or just exit the Terminal?

    A pain free upgrade, thanks for the pointers.

      @Alan G

      Welcome, we are glad this worked for you. Many thanks for the feedback.

    • Bernard Puga S says:

      Our new concern now is how will move from 18 to 19. Inside the revision I use standard update but for main revision I use reformat and install all automatically using teejee Aptik Migration Utility.

      • Aaron Kili says:


        Once Linux Mint 19 is out(stable version), we will definitely prepare an article about how to upgrade from 18 or a another previous version to it. Thanks for the feedback.

    tiger @ asusik ~ $ mintupgrade upgrade
    Traceback (most recent call last):

    So, instead of beauty and simple guide, upgrade process fail.
    Bad. Very bad.

    It does not work but is it an error in your lines to install mintupgrade rather than mintupdate?
