The repo2docker base image, which powers builds on mybinder.org, is being upgraded from the Ubuntu 18.04-based
buildpack-deps:bionic, which has reached its end of support, to the 22.04-based
buildpack-deps:jammy . Very little in the host system is used by repo2docker (upgrading the version required no other changes to repo2docker), so most repos are unlikely to be affected. But if you use
apt.txt, custom commands that make assumptions about the base system (some package names or versions may have changed), or the system compilers (may be used building dependencies), upgrading the distro version can change things, and your repos may need updating.
As always, let us know here if you have questions or issues, or report bugs.
