Dear Roger, thank you very much, this was exactly the source of the problem. In the computer where /proc was not mounted, /etc/schroot/schroot.conf did not provide a type for the sid schroot, which then defautled to plain. Indicating type=directory solved my problem. It is my mistake that I have misconfigured this system and that it did not use the configuration files in /etc/schroot/chroot.d. When I was trying to solve my problem by myself, I looked for “/proc” as a keyword in the documentation and did not find a hint that not having it mounted was a symptom of not using the type I intended. If you think that others may make a similar error, how about the following patch to the schroot documentation? diff --git a/man/schroot.conf.5.in b/man/schroot.conf.5.in index 40cec0d..92e08b9 100644 --- a/man/schroot.conf.5.in +++ b/man/schroot.conf.5.in @@ -133,7 +133,8 @@ Plain and directory chroots .PP Chroots of type \[oq]plain\[cq] or \[oq]directory\[cq] are directories accessible in the filesystem.
