[Koha] upgrade to Koha 18.11 on Ubuntu 18.04

[Giuseppe Angilella]

Many thanks, Salvo!

The update to Koha 18.11 worked after I issued the command

sudo apt install libhttp-oai-3.27-perl

as you kindly suggested.

I chose to maintain my old /etc/koha/koha-sites.conf , although a later 
comparison with koha-sites.conf.dpkg-dist as provided by the new package 
did not evidence any major difference. (The new configuration does not 
include the options BIBLIOS_INDEXING_MODE="dom" and 
AUTHORITIES_INDEXING_MODE="dom", and by default sets USE_MEMCACHED="yes", 
while I had "no".)

A first run immediately after the update seemed to exhibit some 
inconsistencies in the appearance of the -intra page, but these 
disappeared after a reboot and a page refresh on my browser.

There is some change perhaps in the opac page (e.g. background colour) 
which I may have to reset manually, but one should always be ready to some 
minor change after an upgrade.

While googling for a solution, I've also stumbled in the following bug, 
which I quote for later reference:

Many thanks and best regards,

Giuseppe.
