As mentioned in https://github.com/gitgitgadget/git/issues/345, there is a
Pipeline that builds sparse packages for Ubuntu, ready for use in our CI
build: https://dev.azure.com/git/git/_build?definitionId=10&_a=summary.
Currently, it is scheduled to run every weekday at 5:00am (I assume that's
UTC).

So I went ahead and added more details to the ticket, essentially
demonstrating how the `sparse` package can be downloaded and installed in
the CI build in a Bash step:

-- snip --
urlbase=https://dev.azure.com/git/git/_apis/build/builds
id=$(curl "$urlbase?definitions=10&statusFilter=completed&resultFilter=succeeded&\$top=1" |
	json_pp |
	sed -n 's/^         "id" : \([1-9][0-9]*\).*/\1/p')
download_url="$(curl "$urlbase/$id/artifacts" |
	json_pp |
	sed -n '/^      {/{:1;N;/\n      }/b2;b1;:2;/"name" : "sparse"/{s/.*"downloadUrl" : "\([^"]*\).*/\1/p}}')"
curl -Lo sparse.zip "$download_url"
unzip sparse.zip
sudo dpkg -i sparse/*.deb
-- snap --

It is quite likely that the ugly and unwieldy `json_pp | sed` things could
be replaced by elegant `jq` calls.

Ciao,
Dscho
