Some VPS providers don't have a Debian 8 template to build your VPS from. Just Debian 7. So you need to do the upgrade yourself. Not a big task, but there is the change to systemd to consider. So here are the commands that you need for this. After changing all references to wheezy in your /etc/apt/sources.list file to jessie:
# update with the new sources.list apt-get update # Make aure you have all the keys you need apt-get install --reinstall debian-archive-keyring # In case you're coming from a minimal Debian 7 template apt-get -y install dialog # In case your locale is not setup, again, coming from a minial template dpkg-reconfigure locales # The upgrade apt-get dist-upgrade # Check the version upgrade has taken place lsb_release -a # or cat /etc/debian_version # Swap out upstart with systemd apt-get -y install systemd systemd-sysv # Need to force a reboot I found as init is not working due to the above reboot -f # Check systemd and not upstart is running ps aux|grep '(systemd|upstart)' # Remove upstart and its files apt-get -y purge upstart rm -fr /var/log/upstart # DoneIf you have a messy of a source.list(.d) then you can build a clean one here Ref: http://justinfranks.com/linux-administration/upgrade-openvz-vps-from-debian-7-wheezy-64-bit-to-debian-8-jessie-64-bit
