Comment 4 for bug 1738412

I can confirm that this is missing in Xenial&Zesty but Fixed in Artful+ as mentioned in comment #3.

The fix came in by:
https://anonscm.debian.org/cgit/pkg-squid/pkg-squid.git/commit/?id=444a7fb4df59a76e6aa2741eb7a245587ccce4b3

That is in 3.15.12 and Xenial has 3.5.12-1ubuntu7.
But due to the different times the renaming squid3/squid happened Xenial and Zesty are affected.

One would need to apply above linked patch to debian/squid.rc (without the 3).

@Rbasak - you might have some extra context on that renaming history, I'm subscribing you and Ubuntu-server would you mind to take a look?
