Title: lxc-attach does not output stderr any more if stdout is redirected Status in lxc package in Ubuntu: Fix Released Bug description: With lxc 2.0.0~rc5-0ubuntu1 the autopkgtest LXC runner is still broken (even with bug 1551960 fixed) when stderr is a terminal: $ adt-run gzip --- lxc -s adt-wily [...] adt-run [10:15:45]: ERROR: erroneous package: got 10 lines of results from extract where 4 expected: gpgv: Signature made Mon 27 Oct 2014 09:48:46 AM CET using RSA key ID BD4CA59E gpgv: Can't check signature: public key not found dpkg-source: warning: failed to verify signature on ./gzip_1.6-4ubuntu1.dsc Get:1 http://archive.ubuntu.com/ubuntu/ wily/main gzip 1.6-4ubuntu1 (dsc) [1,907 B] Get:2 http://archive.ubuntu.com/ubuntu/ wily/main gzip 1.6-4ubuntu1 (tar) [1,075 kB] Get:3 http://archive.ubuntu.com/ubuntu/ wily/main gzip 1.6-4ubuntu1 (diff) [14.9 kB] /tmp/adt-virt-lxc.shared.xklzp9z7/downtmp/build.ehH/gzip-1.6 gzip 1.6-4ubuntu1 1 Thie first couple of lines are supposed to go to stderr, not stdout. This works if stderr is not a terminal, but a pipe, with e. g. "adt- run -l /dev/null gzip --- lxc -s adt-wily" (where stderr is sent to a pipe which gets tee'ed to both the log file and the real stderr). This is probably a regression in LXC, and it doesn't happen with older LXC nor LXD nor any other backend. But it might also be some intentional change which autopkgtest needs to be adjusted to, so for now I keep tasks for both projects.
