Hi, I have updated sbuild to 0.91.5~bpo13+1 under stable environment.
I see the same problem and even worse it shows up in default setting since sbuild's default has been updated to use unshare. By explicitly setting to schroot, no more issue. --- 0m0.0s DEBUG: Command ok: ['dpkg', '--info', '/home/osamu/salsa/debmake/debmake_5.1.3_all.deb'] 0m0.0s DEBUG: Starting command: ['schroot', '--begin-session', '--chroot', 'unstable-amd64-sbuild', '--session-name', 'unstable-amd64-sbuild-1f46ee10-04a4- 11f1-8000-498bdfd79633-piuparts'] 0m0.0s DUMP: E: /etc/schroot/schroot.conf: File is not owned by user root 0m0.0s ERROR: Command failed (status=1): ['schroot', '--begin-session', '-- chroot', 'unstable-amd64-sbuild', '--session-name', 'unstable-amd64-sbuild- 1f46ee10-04a4-11f1-8000-498bdfd79633-piuparts'] E: /etc/schroot/schroot.conf: File is not owned by user root 0m0.0s ERROR: piuparts run ends. ---
