A fix to a probably a bug? "Linux Lite cannot check for Updates"

[ralphy]

Yes, there are other tools than curl, for example 'wget', but it does not help much if curl is hard-coded into the
update script.

A fallback function could be added to deal with this:

Code:

if which curl > /dev/null; then
    echo "use curl"
else
    echo "use wget"
fi

But the real issue is to find out why curl is being removed. It shouldn't be uninstalled just because... that's what's needs fixing.
