This looks like it's down to a naughty developer :)

[[ is a 'bashism' (so-called because it's something that exists in
bash but not in the 'sh' that it's a development from).

The command 'sh test.sh' passes the 'test.sh' script to 'sh' which is
a shell. Normally and historically it's a link to /bin/bash but
modern Ubuntus and Debians use dash instead (in the interests of
speed). [[ doesn't work in dash, so the test script fails on that error
and the install aborts.

It should be a simple fix - the invocation of that script should be

bash test.sh

rather than

sh test.sh

Of scripting, bash would be more helpful here. Perhaps most useful
would be experience installing Perl apps, but that's rather niche :)

Really, this is less bash scripting and more simply using bash, but the
easiest way to use bash is to automate it into scripts.
