Public bug reported: Hi,
First of all, thank you for running and maintaining Ubuntu, its a very valuable system and community and probably tons of work. I ran into a strange issue when attempting to install nodejs and npm on Ubuntu 22.04.1 LTS (amd64), the dependency resolution appears to be illogical. In particular, the output of command #5 below doesn´t appear to make any sense: why would `sudo apt install nodejs=12.22.9~dfsg-1ubuntu3.4` attempt to install libnode72 `12.22.12~dfsg-1~deb11u4` which is incompatible instead of `12.22.9~dfsg-1ubuntu3.4` which is in the dependency chain? Manually installing `sudo apt install libnode72=12.22.9~dfsg-1ubuntu3.4` followed by `sudo apt install nodejs=12.22.9~dfsg-1ubuntu3.4` does appear to complete without errors, therefore the metadata encoded in the packages is correct. When I then try to install `sudo apt install npm` I run into the same issue: nodejs : Depends: libnode72 (= 12.22.9~dfsg-1ubuntu3.4) but 12.22.12~dfsg-1~deb11u4 is to be installed It appears like the dependency resolver is not behaving correctly. I am not sure how actionable this is, perhaps there is something wrong with my computer. But it does not behave in the way that a normal user would expect, so just posting this in case others might have run into something similar. Some additional links and commandline output which might assist in troubleshooting and for future reference: Package: nodejs (12.22.9~dfsg-1ubuntu3.4 and others) https://packages.ubuntu.com/jammy/nodejs depends on Package: libnode72 (12.22.9~dfsg-1ubuntu3.4 and others) https://packages.ubuntu.com/jammy/libnode72 and suggests Package: npm (8.5.1~ds-1) https://packages.ubuntu.com/jammy/npm I apparently have both Ubuntu and Debian repos configured in `/etc/apt/sources.list`: ``` # Ubuntu 22.04.1 LTS deb http://us.archive.ubuntu.com/ubuntu/ jammy universe deb http://us.archive.ubuntu.com/ubuntu/ jammy-updates universe # Debian Bullseye deb http://deb.debian.org/debian bullseye main contrib universe multiverse non-free deb http://deb.debian.org/debian bullseye-updates main contrib universe multiverse non-free ``` However, `sudo apt -o Debug::pkgProblemResolver=yes upgrade` does not show any conflicts: Reading package lists...
