I installed the metche 1.0-1 debian package on my Debian GNU/Linux box. A few days later, I wanted to add the package versions support, by installing apt-show-versions and updating metche.conf with DO_PACKAGES="yes". The result is metche failing on the packages part of the job, with this log:
++ mktemp -q
+ tmp_packages=/tmp/tmp.pthVJG
+ apt-show-versions -i
+ apt-show-versions
+ sort
+ diff -wEbB /var/lib/metche/testing-latest.packages /tmp/tmp.pthVJG
+ grep -v '^[0-9-]'
diff: /var/lib/metche/testing-latest.packages: No such file or directory
Seems that metche can't handle packages if DO_PACKAGES is not configured "yes" from the beginning.
