From the log from the initial report: I: using /tmpfs/foo/mmdebstrap.wYxMFPcZHA as tempdir This directory is created and owned by unshared user. Afterwards mmdebstrap tries to create another temporary directory in /tmpfs/foo (instead of /tmpfs/foo/mmdebstrap.wYxMFPcZHA) and fails. I expect that mmdebstrap would succeed if it would create additional temporary directories in that initial /tmpfs/foo/mmdebstrap.wYxMFPcZHA directory. > Also: the sticky bit probably has no influence on whether or not you > get the > "permission denied" error, right? Yes. The sticky bit has no effect on the "permission denied" error. I just mentioned it, because /tmp has mode 1777. -- Benjamin Drung DevOps Engineer and Debian & Ubuntu Developer Platform Integration (IONOS Cloud) 1&1 IONOS SE | Greifswalder Str. 207 | 10405 Berlin | Germany E-mail: benjamin.dr...@cloud.ionos.com | Web: www.ionos.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Dr. Christian Böing, Hüseyin Dogan, Dr. Martin Endreß, Hans- Henning Kettler, Matthias Steinberg, Achim Weiß Aufsichtsratsvorsitzender: Markus Kadelke Member of United Internet Diese E-Mail kann vertrauliche und/oder gesetzlich geschützte Informationen enthalten.
