So, I was doing something stupid in debian. Going with the testing branch for a few files, and had an issue.

Setting up runit (2.1.1-6) ...
dpkg: error processing runit (--configure):
subprocess installed post-installation script returned error exit status 10
Errors were encountered while processing:
runit


How to fix? Easy.
Delete /var/lib/dpkg/info/runit* and /var/cache/apt/archives/runit* and it works fine.

I actually moved the files first, just to verify it.

and to get the list I did this.

ls /var/cache/apt/archives/ |grep runit >> /root/info

ls list screen |grep (search) the files that i am looking for, >> append it to this file. So I can look thru it later.
