Package: mmdebstrap Version: 0.3.0-10 Severity: wishlist Hi Josch,
If you backport mmdebstrap to stretch (yes, that's relatively easy after downgrading debhelper compatibility and dependency), you can observe the following interaction: # grep VERSION_ID /etc/os-release VERSION_ID="9" # mmdebstrap buster /target I: automatically chosen mode: root I: chroot architecture amd64 is equal to the host's architecture I: running apt-get update... done I: downloading packages with apt... done I: extracting archives... done I: installing packages... done I: downloading apt... done I: installing apt... done I: installing remaining packages inside the chroot... done I: cleaning package lists and apt cache... done Reading package lists... W: Problem unlinking the file auxfiles - Clean (21: Is a directory) apt-get --option Dir::Etc::SourceList=/dev/null update failed at /usr/bin/mmdebstrap line 569. # echo $? 1 # I guess this is due to some interaction between stretch's apt and buster's apt. The resulting chroot looks like it works otherwise. If you don't want to diagnose this, please just close it as wontfix. I can fully understand that. Helmut
