Anyone who is caught in this position can use these commands (as root): cat <<EOF >/etc/apt/preferences.d/proposed-updates Package: * Pin: release a=focal-proposed Pin-Priority: 400 Package: src:glibc Pin: release a=focal-proposed version 2.31-0ubuntu9.4 Pin-Priority: 500 EOF
cat <<EOF >/etc/apt/sources.list.d/ubuntu-focal-proposed.list # Enable Ubuntu proposed archive deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted main multiverse universe EOF And then updating in the usual way to test the 9.4 update without the risk of getting other packages from the proposed pocket onto their system. And I'd definitely appreciate hearing if works!
