[L. P. Luigi Espenlaub]

Public bug reported:

**This is the second try at posting this due to an "Oops, something went
wrong" message**

I am entering this bug on a different machine due to the unstable state
of my wife's machine

the repair broken packages and I assume ubuntu-release-upgrader-core has same error because of trying to fetch libcgi-pm-perl_4.26-1_all.deb from 
Http://us.archive.ubuntu.com/ubuntu/pool/main/libc/libcgi-pm-perl_4.26-1_all.deb
when it should be fetching from:
Http://us.archive.ubuntu.com/ubuntu/pool/main/libc/libcgi-pm-perl/libcgi-pm-perl_4.26-1_all.deb
same for:
libcgi-pm-perl_0.77-1build1_amd64.deb
and
libcgi-pm-fast-per1_2.10-1_all.deb

in each case the directory /libcgi-pm-perl/ has been left out of the
fetch path.

Cannot include log files contained in 
"/var/log/dist-upgrade/"
cd var
returns 
no such file or directory

What I did
===============================

ubuntu with linux 4.4.0-34-generic (recovery mode)
