Fabian, if you don't like docker for some reasons, I can show way howto reproduce problem with debootstap.
Just for information, I have RaspberryPI with Ubuntu 22.04.5 LTS and debootstap 1.0.142 taken from Debian Forky (https://packages.debian.org/forky/debootstrap) ``` ubuntu@ubuntu:~$ debootstrap --version debootstrap 1.0.142 ubuntu@ubuntu:~$ apt list --installed | grep debootstrap WARNING: apt does not have a stable CLI interface. Use with caution in scripts. debootstrap/now 1.0.142 all [installed,local] ubuntu@ubuntu:~$ ``` Let's try to reproduce a problem. Create Debian Bookworm chroot environment in minbase variant: ``` sudo debootstrap --no-check-sig --variant=minbase bookworm bookworm- chroot-env http://deb.debian.org/debian/ |& tee debootstrap.log ``` debootstrap.log attached to letter just for information. Only main bookworm repo exists in sources list at this moment: ``` ubuntu@ubuntu:~$ cat bookworm-chroot-env/etc/apt/sources.list deb http://deb.debian.org/debian bookworm main ubuntu@ubuntu:~$ ls bookworm-chroot-env/etc/apt/sources.list.d/ ubuntu@ubuntu:~$ ``` Add deb-src: ``` echo "deb-src http://deb.debian.org/debian bookworm main" | sudo tee -a bookworm-chroot-env/etc/apt/sources.list ``` sources.list after this change looks like this: ``` ubuntu@ubuntu:~$ cat bookworm-chroot-env/etc/apt/sources.list deb http://deb.debian.org/debian bookworm main deb-src http://deb.debian.org/debian bookworm main ubuntu@ubuntu:~$ ``` Chroot in created environment: ``` sudo chroot bookworm-chroot-env bash ``` Update apt cache: ``` apt update ``` Output in my case: ``` root@ubuntu:/# apt update Hit:1 http://deb.debian.org/debian bookworm InRelease Get:2 http://deb.debian.org/debian bookworm/main Sources [9494 kB] Get:3 http://deb.debian.org/debian bookworm/main Translation-en [6109 kB] Fetched 15.6 MB in 8s (1918 kB/s) Reading package lists... Done Building dependency tree... Done All packages are up to date. root@ubuntu:/# ``` And now we can see problem just like in docker earlier in this thread: ``` root@ubuntu:/# apt -s build-dep rustc Reading package lists... Done Reading package lists... Done Building dependency tree... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libstd-rust-web-dev : Conflicts: libstd-rust-dev rustc-web : Conflicts: rustc E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. root@ubuntu:/# ``` I also checked Debian Bookworm chroot env created in described way in amd64. I reprpoduced problem in described way. P.S. We can try to reproduce problem in chroot environment with Trixie created using debootstrap: ``` sudo debootstrap --no-check-sig --variant=minbase trixie trixie-chroot- env http://deb.debian.org/debian/ |& tee debootstrap.log ``` But `apt -s build-dep rustc` works ok in Debian Trixie arm64 and amd64.
