deb-get does not recognize Linux Mint Debian Edition (LMDE) as a supported release

[jruschme]

Expected behavior

deb-get should recognize LMDE 5 (Elsie) as Debian bullseye

Actual behavior

deb-get reports "Linux Mint Elsie is not supported because it is not derived from a supported Debian or Ubuntu release."

Steps to reproduce

Install deb-get on LMDE 5.
Run 'deb-get' from root prompt.

From a quick look at the code, it appears that the root cause is that a Debian-derived distro is expected to have a Debian codename as the VERSION_CODENAME in /etc/os-release. LMDE, however, is more like their Ubuntu-based counterpart in that they put the debian version in a DEBIAN_CODENAME variable in /etc/os-release.

OK, I'll try to come up with a solution.

I have the same issue running Debian Bookworm.
