Start the session
Debian
Jessie to Stretch
export new=stretch export old=jessie
Stretch to Buster
export new=buster export old=stretch
Buster to Bullseye
export new=bullseye export old=buster
Devuan
Ascii to Beowulf
export new=beowulf export old=ascii
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-${old} -s /dev/vg*/log
Disable config management, etc.
zile /etc/default/aptitude-robot
Do the upgrade step by step with aptitude
sed -e "s/${old}/${new}/gi" -i /etc/apt/sources.list /etc/apt/sources.list.d/*.{list,sources}
sed -e 's:bullseye/updates:bullseye-security:g' -i /etc/apt/sources.list /etc/apt/sources.list.d/*.{list,sources}
aptitude -u
Enable automatic package updates again
zile /etc/default/aptitude-robot
Running this will enable the remaining disabled stuff anyways.
Reboot
shutdown -r now "New kernel after dist-upgrade to ${new}"
