Package: pbuilder Version: 0.230.4 Severity: important Tags: upstream Hi,
I tried to upgrade my Docker-based pbuilder containers from stretch to buster. However it appears that pbuilder and/or debootstrap do not work properly inside Docker containers any longer due to issues with mounting special filesystems such as proc and devpts. The issue can be reproduced easily in a Debian Buster based container: # docker run --privileged -it debian:buster /bin/bash root@d81f634fe4a0:/# cat /proc/mounts overlay / overlay rw,relatime,lowerdir=/var/lib/docker/overlay2/l/TPOD4JNRBNCTMXNHYCY5XVRBQ3:/var/lib/docker/overlay2/l/TSD62UVCIJQ2LJ4XTUHKTVEK77,upperdir=/var/lib/docker/overlay2/aa29cac2d0ebecfb12fdd71a9952845140052615f2bd746c4336daa8d7a4d533/diff,workdir=/var/lib/docker/overlay2/aa29cac2d0ebecfb12fdd71a9952845140052615f2bd746c4336daa8d7a4d533/work 0 0 proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0 tmpfs /dev tmpfs rw,nosuid,size=65536k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=666 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 tmpfs /sys/fs/cgroup tmpfs rw,nosuid,nodev,noexec,relatime,mode=755 0 0 cgroup /sys/fs/cgroup/systemd cgroup rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd 0 0 cgroup /sys/fs/cgroup/devices cgroup rw,nosuid,nodev,noexec,relatime,devices 0 0 cgroup /sys/fs/cgroup/freezer cgroup rw,nosuid,nodev,noexec,relatime,freezer 0 0 cgroup /sys/fs/cgroup/net_cls,net_prio cgroup rw,nosuid,nodev,noexec,relatime,net_cls,net_prio 0 0 cgroup /sys/fs/cgroup/pids cgroup rw,nosuid,nodev,noexec,relatime,pids 0 0 cgroup /sys/fs/cgroup/memory cgroup rw,nosuid,nodev,noexec,relatime,memory 0 0 cgroup /sys/fs/cgroup/blkio cgroup rw,nosuid,nodev,noexec,relatime,blkio 0 0 cgroup /sys/fs/cgroup/cpuset cgroup rw,nosuid,nodev,noexec,relatime,cpuset 0 0 cgroup /sys/fs/cgroup/cpu,cpuacct cgroup rw,nosuid,nodev,noexec,relatime,cpu,cpuacct 0 0 cgroup /sys/fs/cgroup/perf_event cgroup rw,nosuid,nodev,noexec,relatime,perf_event 0 0 mqueue /dev/mqueue mqueue rw,nosuid,nodev,noexec,relatime 0 0 /dev/sdb /etc/resolv.conf ext4 rw,noatime,nodiratime,commit=300,data=ordered 0 0 /dev/sdb /etc/hostname ext4 rw,noatime,nodiratime,commit=300,data=ordered 0 0 /dev/sdb /etc/hosts ext4 rw,noatime,nodiratime,commit=300,data=ordered 0 0 shm /dev/shm tmpfs rw,nosuid,nodev,noexec,relatime,size=65536k 0 0 devpts /dev/console devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=666 0 0 root@d81f634fe4a0:/# apt-get update && apt-get -y --no-install-recommends install pbuilder [...] root@d81f634fe4a0:/# pbuilder create --distribution buster W: /root/.pbuilderrc does not exist W: cgroups are not available on the host, not using them.

Thank you for looking into this issue. Until then I'll continue to use the stretch-based pbuilder container and use it to build packages for buster.
