I tried to reproduce the problem. After having installed libpam-tmpdir I get
the same errors as you do, so success!

But now I wonder how to fix the problem. It seems that the package sets $TMP
and $TMPDIR to /tmp/user/1000 for me. I guess the last bit is my user id. But
then it fails to create that last component of that directory. This is why
dpkg-deb in your log is unable to create a temporary directory. The path that
$TMP and $TMPDIR are set to simply doesn't exist. At least on my system.

Can you confirm that observation?

Thanks!

cheers, josch
