Upgrading to Ubuntu Xenial 16.04 LTS on OpenVZ RHEL 2.6.32 kernel VPS?

LunicsLunics Member

Hi,

I tried to upgrade my VPSdime VPS from Ubuntu 14.04 to 16.04. There were no errors during the upgrade, only a warning about the 2.6.32 kernel being unsupported by libc6 (to be supported you need to run kernel 3.2 or newer).

After the reboot, however, the SSH server is not starting up. I do not have access to the console so I don't know what went wrong.

Has anyone gotten Ubuntu 16.04 to work with a OpenVZ VPS running the RHEL6 kernel?

    Here's an article that may be of use? (It's 15.04 to 16.04 on OpenVZ) - https://it-offshore.co.uk/linux/ubuntu/67-upgrading-ubuntu-15-04-to-16-04-in-openvz

    I don't have any current openvz plans at the moment to try the upgrade from 14.04 to 16.04 but I'll be purchasing an openvz vps tomorrow and will play around with it.

    personally I do not recommend doing a full dist upgrade in openvz. It is better to reinstall to the newer version. You usually have less issues

    There's no OpenVZ Ubuntu 16.04 templates though

    The official OVZ templates for 16.04 will probably appear pretty quickly (given the popularity of Ubuntu), but I'm afraid not today or tomorrow or the day after tomorrow ...

  • @Lunics How do you upgrade in a openvz? Everytime I tried to upgrade, it always fail in one way or another.

  • I just did the usual "apt-get update; apt-get dist-upgrade" after changing the sources.list

  • With systemd and new libc running on ancient kernel, you are pretty much on your own.

    And TBH I'd be surprised if you didn't brick your system.

    Is VNC provided with the VPS? If so, you should be able to mount the ISO/Img file and install upon boot.

    In the case of OVZ, I would really wait until an official template for 16.04 is released and then do a clean install. (Yes, patience.) It would really surprise me if an upgrade with apt-get to a major version number succeeded without problems.

    @Lunics I purchased an OpenVZ VPS from MikroVPS today and I upgraded to Ubuntu 16.04 with no problems.

    I installed update-manager-core and then I did a do-release-upgrade and once the upgrade was finished I disabled systemd-bootchart and systemd-sysctl then rebooted and everything works.
