Debian 10 to 11¶
Pre update check¶
Stretch check¶
Check if any sources still point to stretch
cd /etc/apt grep -nr stretch .
If so, bring those up to buster and run updates first
https://redmine.palantetech.coop/projects/commons/wiki/Debian_9_to_10
Metapackage check¶
Check to make sure kernel metapackage is installed, not just specific kernel
dpkg -l "linux-image*" | grep ^ii | grep -i meta
should have results
If not, install metapackage
https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html#kernel-metapackage
Purged package check¶
List and purge removed packages with config files remaining
https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html#purge-removed-packages
aptitude search '~c' aptitude purge '~c'
Hold check¶
These commands should have no results
aptitude search "~ahold" dpkg --get-selections | grep 'hold$'
Update sources list¶
Check which sources exist that point to buster
cd /etc/apt grep -nr buster .
Edit the main list, and any others that come up
vim /etc/apt/sources.list
replace buster with bullseye
:%s/buster/bullseye/g
replace bullseye/updates with bullseye-security
:%s/bullseye\/updates/bullseye-security/g
https://www.debian.org/releases/bullseye/amd64/release-notes/ch-information.en.html#security-archive
Upgrade the system¶
Update the sources¶
apt-get update
If you get a NO_PUBKEY error, see https://redmine.palantetech.coop/projects/commons/wiki/Debian_10_to_11#Common-problems
Check for Necessary Disk Space¶
apt-get -o APT::Get::Trivial-Only=true dist-upgrade
Minimal Upgrade¶
apt-get upgrade
- if it asks whether to change /etc/apt/trusted.gpg.d/debian-archive-jessie-security-automatic.gpg, say yes
- other things it asks to change, say no, keep the existing file
Full Upgrade¶
apt-get dist-upgrade
Change configs during full upgrade?¶
package | change configs |
nrpe | no |
sudoers | no |
journald | no |
backupninja | no |
nginx | yes but recheck after |
redis | yes but recheck after |
sshd_config | yes |
glibc | yes |
Upgrade MySQL databases (if MySQL/MariaDB installed)¶
mysql_upgrade
Check that things are up¶
- if a web server, make sure websites are up
- if an infrastructure server, test and make sure all parts of the infrastructure are working properly
- if a PTC server check the recovery plan entry for that server to make sure everything has recovered
Check what packages were removed¶
cat /var/log/apt/history.log | grep Remove
- copy that into ongoing updates documentation for records
- Make sure there was nothing important in there
- If there were important packages in there
- check aptitude to see if newer versions were already installed
- check debian package search to search for what version is appropriate
- https://packages.debian.org/
Common problems¶
NO_PUBKEY during update
W: GPG error: https://apt.postgresql.org/pub/repos/apt bullseye-pgdg InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7FCC7D46ACCC4CF8
