My common steps to do a dist-upgrade to a new Debian stable release. Based on https://www.debian.org/releases/stable/amd64/release-notes/ch-upgrading.en.html but optimised for direct copy and paste, i.e. no italic step pseudo-variables necessary. And it of courses uses aptitude interactively to upgrade machines while keeping services downtimes as short as possible.
Start the session
Wheezy to Jessie
export new=jessie export old=wheezy
Jessie to Stretch
export new=stretch export old=jessie
Generic
screen -U script -t 2>~/upgrade-${new}.time -a ~/upgrade-${new}.script
Common Checks
dpkg --audit dpkg --get-selections "*" > ~/curr-pkgs.${old}.txt aptitude search "~ahold" dpkg --get-selections | grep 'hold$'
Check if all packages are uptodate and if there are obsolete and local packages installed
aptitude -u
Make LVM snapshots if needed/wanted/possible
lvcreate -L 3G -n root-${old} -s /dev/vg*/root lvcreate -L 5G -n var-${old} -s /dev/vg*/var lvcreate -L 1G -n log-${old} -s /dev/vg*/log
Disable config management, etc.
zile /etc/default/aptitude-robot /etc/dphys-config
Make some config backups for easy reference
Specific for Jessie: Apache 2.2 -> 2.4
cd /etc && tar cvzf apache2-${old}.tgz apache2
Do the upgrade step by step with aptitude
sed -e "s/${old}/${new}/gi" -i /etc/apt/sources.list /etc/apt/sources.list.d/*.list aptitude -u
Cleanup of local stuff
chown -Rc xymon /var/lib/hwerr/ adduser xymon adm service xymon-client restart
Enable config management again
- Switch host to new Debian stable release in config management
zile /etc/dphys-config dphys-config -i
Running this will enable the remaining disabled stuff anyways.
Reboot
shutdown -r now "New kernel after dist-upgrade to ${new}"
