Upgrade to ocng-utils-4.5.
Retry apt-get commands in case of failure.

[imported from fahinstall b1e866a54b3215315b724dfe71ff48efc2078d87]

apt-get may fail due to not being able to acquire apt lock
(most commonly caused by parallel aptd startup).

Try apt-get commands up to 5 times (every 5 seconds) using bash wrapper
function.
Pre-create .lesshst.
