This is done with two changes:
* Get the current release with `lsb_release` instead of parsing
non-deb822 sources.list file. This is because `noble` is
deb822-only, thus the old parsing fails.
* Move away from `apt-key`. This tool has been deprecated after Jammy
and shouldn't be used anymore.
fix: web: fix no content-length header for static file endpoints
britney recently started having an issue with downloading the
autopkgtest.db - suddenly the static endpoint had stopped returning the
"Content-Length" header for these static get requests.
It was verified in staging that apache2/2.4.41-4ubuntu3.17 was the
problematic version - I tested apache2/2.4.41-4ubuntu3.16 and the
Content-Length header was present when downloading the db.
The header was no longer present because apache2 now serves static files
by default with the "chunked" transfer-encoding, rather than the
"identity" transfer-encoding (which includes the Content-Length header,
Content-Length header is not compatible with a chunked transfer
encoding, see [1]).
Was opened, where a discussion with the package maintainer was had, and
the conclusion was that this new behaviour by default was intended and
is a necessary security patch.
Which helpfully had a solution that I modified for our web app.
All static files with the config present in this commit now get served
with the "identity" transfer-encoding and have the appropriate
Content-Length header.
