I installed the Debian app from Microsoft store which gets me the command line Debian.
I then tried to add the Salsa repo to be able to install EDU packages. $ cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 11 (bullseye)" NAME="Debian GNU/Linux" VERSION_ID="11" VERSION="11 (bullseye)" VERSION_CODENAME=bullseye ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL=https://bugs.debian.org/ I tried $ sudo apt-add-repository http://salsa.debian.org/debian-edu But needed this first $ sudo sudo apt-get install software-properties-common Now I get from apt update… Err:5 https://salsa.debian.org/debian-edu bullseye InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) Reading package lists... Done E: Failed to fetch http://salsa.debian.org/debian-edu/dists/bullseye/InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) E: The repository 'http://salsa.debian.org/debian-edu bullseye InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. How can I proceed to get EDU packages with default Debian from WSL2 Microsoft Store install of Debian 11 ? Lee T.
