Hi, Andrey Rakhmatullin suggested to use: mmdebstrap --chrooted-customize-hook=bash unstable /dev/null
for the bootstrap test, so now I can say it fails in a chroot too. So in short: - it fails on my account on my box ; - it fails on a new account on my box ; - it fails in a chroot on my box... and I still don't know why. Cheers, JP
