retitle 751575 schroot fails with /dev/fd/62: No such file or directory thanks
Hey Neil, Neil Williams [2014-06-14 13:46 +0100]: > E: Can not write log (Is /dev/pts mounted?) - openpty (2: No such file or > directory) > Setting up adt-satdep (0) ... This error from apt might be insightful: Which profile does your schroot use, and what is your corresponding /etc/schroot/<profile>/fstab ? I use the "default" profile for my schroots which bind-mounts /dev/, /dev/pts, and /dev/shm. The "sbuild" profile still bind-mounts /dev/pts, so I suppose you are using something else. However, even if I comment out /dev/pts from /etc/schroot/sbuild/fstab, I do get this error from apt (which doesn't stop autopkgtest), but I still don't get the main error: > adt-run [2014-06-14 13:39:52]: & apt0t-testsuite: [----------------------- > bash: line 10: /dev/fd/62: No such file or directory I think the most likely explanation for this is that your schroot doesn't have /proc bind-mounted, as /dev/fd is usually a symlink to /proc/self/fd (please double-check in your schroot). If I comment out the /proc bind mount from /etc/schroot/*/profile, I get exactly the same error. If you use any kind of nontrivial stdin/out/err redirections in dash/bash that will use /dev/fd/ rather heavily. A lot of other stuff will also fail without /proc/ in your schroot, so I'm rather surprised that you never noticed that? So to guard against this I could add an explicit test for "bind-mounted /proc" to the schroot runner; but a schroot without /proc is rather useless, so it's a bit of a surprise that folks have them in the first place :-) Thanks, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
