Package: sbuild
Version: 0.79.1-1
Severity: normal
Hi,
I have tried to get sbuild working in unshare mode. Here are the steps I
have followed, from what I understood they should be sufficient:
sudo sysctl kernel.unprivileged_userns_clone=1
sbuild-createchroot --chroot-mode=unshare --make-sbuild-tarball
~/.cache/sbuild/sid-amd64.tar.gz sid `mktemp -d` http://deb.debian.org/debian/
sbuild -d sid hello
The last step is unsuccessful, it seems to fail to execute any comment.
I have attached the output of the last command running with debug in
case it could help.
I have also tried to unpack the tarball and run the following command:
unshare -f -U -r -p -m --mount-proc -R sid
It works find, so it seems to show that the chroot creating is not
totally broken.
Thanks,
Aurelien

Thanks for your answer. I was not able to get it working that way (perl
complains it can't find strict.pm), however after building the package
from git and installing it, I confirm everything works as expected.
Thanks for the help.
I am therefore closing the bug.
