I can't reproduce the problem: | root@dd10c07bc0f9:/# DEBIAN_FRONTEND='noninteractive' apt install pbuilder --no-install-recommends | [...] | Preconfiguring packages ... | Configuring pbuilder | -------------------- | | Default mirror not found | | Mirror information detection failed and the user provided no mirror | information. | | Please enter valid mirror information. | | Selecting previously unselected package bzip2. | (Reading database ... 4935 files and directories currently | installed.) | [...] | root@dd10c07bc0f9:/# grep '^MIRROR' /etc/pbuilderrc | MIRRORSITE=http://deb.debian.org/debian Same behavior for both bookworm + trixie. But I agree that we should add support for deb822. AFAIK there sadly is no nice interface to query apt for its repositories, but this seems to work for me: https://salsa.debian.org/pbuilder-team/pbuilder/-/merge_requests/41 regards -mika-
