After upgrading to 0.215+nmu1, pbuilder tells me various times during
a build:

ccache: failed to create /var/cache/pbuilder/ccacheLD_PRELOAD= (Permission denied)
dpkg-architecture: warning: Couldn't determine gcc system type, falling back to default (native compilation)

Adding a 'set -x' into /usr/lib/pbuilder/pbuilder-buildpackage shows:

I: Setting up ccache
+ SUTOUSER='/usr/bin/unshare -n --  env CCACHE_DIR=/var/cache/pbuilder/ccacheLD_PRELOAD= LOGNAME=pbuilder /sbin/start-stop-daemon --start --pidfile /dev/null --chuid pbuilder --startas /bin/sh'

Looks like a missing space ...

And indeed, either of the two following options work:

Change
SUTOUSER=${SUTOUSER/ env / env $CCACHE_ENV}
to
SUTOUSER=${SUTOUSER/ env / env $CCACHE_ENV }
in /usr/lib/pbuilder/pbuilder-buildpackage, line 118

or change
        CCACHE_ENV="CCACHE_DIR=$CCACHEDIR"
to
        CCACHE_ENV="CCACHE_DIR=$CCACHEDIR "
in /usr/lib/pbuilder/pbuilder-buildpackage-funcs, line 110.


Cheers,
gregor
