- Update Docker images on AReS server (linode20) and reboot the server:
# docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | grep -v none | xargs -L1 docker pull
- I decided to upgrade linode20 from Ubuntu 18.04 to 20.04
- First running all existing updates, taking some backups, checking for broken packages, and then rebooting:
# apt update && apt dist-upgrade
# apt autoremove && apt autoclean
# check for any packages with residual configs we can purge
# dpkg -l | grep -E '^rc' | awk '{print $2}'
# dpkg -l | grep -E '^rc' | awk '{print $2}' | xargs dpkg -P
# dpkg -C
# dpkg -l > 2021-08-01-linode20-dpkg.txt
# tar -I zstd -cvf 2021-08-01-etc.tar.zst /etc
# reboot
# sed -i 's/bionic/focal/' /etc/apt/sources.list.d/*.list
# do-release-upgrade
- … but of course it hit the libxcrypt bug
- I had to get a copy of libcrypt.so.1.1.0 from a working Ubuntu 20.04 system and finish the upgrade manually
# apt install -f
# apt dist-upgrade
# reboot
- After rebooting I purged all packages with residual configs and cleaned up again:
# dpkg -l | grep -E '^rc' | awk '{print $2}' | xargs dpkg -P
# apt autoremove && apt autoclean
