    I don’t know what the f*** is wrong with my own system, ve tried every damn thing, keeps reporting back to me that my system is up to date. It does not inform me about the newest version. also tried upgrading using the command “sudo do-releae-upgrade” and “sudo do-release-upgrade -d”, still same s*** – no new release. Right now, I’m as confused as Mr Bean with no clue of what to do. save a life here pls.

    Hi, thank you for the tutorial, Do you know if I will maintain all programs that I have installed on ubuntu 15.10 without any problem?

      Hi, all applications will remain and work after upgrading. Don’t worry about that. However, some third party PPAs will be disabled while upgrading. You can enable enable them after upgrading your Ubuntu. I upgraded my production system from Ubuntu 14.04 to 16.04. Not a single application or single file is gone. Everything worked well.

    Hey, I am sorry to hear that you can’t upgrade to 16.04. Could you please elaborate the question? What is your current Ubuntu version? Did you reboot the system after running command “sudo apt-get update && sudo apt-get dist-upgrade”? Also, make sure you have correct entries in “/etc/update-manager/release-upgrades” file. You should set “prompt=normal” in “/etc/update-manager/release-upgrades” file if you are trying to upgrade from 15.10 to 16.04, and set “prompt-lts” if you are trying to upgrade from 14.04 to 16.04. Feel free to let me know if you need any further assistance. I will gladly help you.

      thanks a lot man. i was able to fix the issue eventually by setting the update option under ‘software & updates’ to check ‘for any new version’ as stated in the official ubuntu release note of 16.04 that 15.10 users should set ‘notify me of a new ubuntu version’ drop down menu to check ‘for any new version’. couldn’t believe it. imagine, such a small thing. anyway, thank you so much i really appreciate ur concern.

    Hello,

    It is an excellent howto-guide. After upgrading from 15.04 to 16.04 (server) all my php websites do not longer work. For example phpinfo.php gives a blank page, phpmyadmin gives a blank page and while logging on to wordpress it gives a blank page too.

    What should I do to get php working again?

    Thanks for your help and with kind regards,
    Willem-Jan

      Hi Willem,

      I really have no idea why php isn’t working after upgrading. Please post the issue along with complete log details in PHP forums.

        Hello,

        Thanks for your reply. I solved it already by creating a new server with Ubuntu 16.04 LTS. Now a clean install, with WordPress restored from a backup, works like a charm.

        With kind regards,
        Willem-Jan
