[Bug 1346736] [NEW] With fastpath-installer deb-line has duplicate slashes in URL

[Nobuto MURATA]

Public bug reported:

When installing a node with fastpath-installer, /etc/apt/sources.list of
the node will look like:

$ cat /etc/apt/sources.list
deb http://archive.ubuntu.com//ubuntu  trusty main restricted universe multiverse
deb http://archive.ubuntu.com//ubuntu  trusty-updates main restricted universe multiverse
deb http://archive.ubuntu.com//ubuntu  trusty-security main restricted universe multiverse
(duplicate slashes just after archive.ubuntu.com)

As far as I understand, squid will have duplicate caches of d-i(one
slash) and fastpath-installer(two slash). Unifying the URLs would help
squid's efficiency.


I tested with multiple slashes below:

$ http_proxy="http://MAAS_IP:8000/" wget http://archive.ubuntu.com/ubuntu/pool/main/libr/librdmacm/librdmacm1_1.0.16-1_amd64.deb 
$ http_proxy="http://MAAS_IP:8000/" wget http://archive.ubuntu.com//ubuntu/pool/main/libr/librdmacm/librdmacm1_1.0.16-1_amd64.deb 
$ http_proxy="http://MAAS_IP:8000/" wget http://archive.ubuntu.com///ubuntu/pool/main/libr/librdmacm/librdmacm1_1.0.16-1_amd64.deb
...
