PostGIS files for PG17-b2

I'm trying to run performance tests for the PG17-b2 release, but like b1 I don't find the PostGIS files there to complete my test suite,  Normally I'd use:

sudo apt install postgresql-17-postgis-3 postgresql-17-postgis-3-scripts

But I don't see any of that available yet for 24.04 Noble Numbat.  Is that normal?  Should I get those from somewhere else?  I know this package repo normally supplies them for the final release.

P.S.:  there is a cat bump for 17b2 and you give out pg_upgrade instructions that correctly move the cluster to the new version.  Works great.  However, the final cleanup step recommended doesn't work:

postgres@rising:~/pgbench-tools$ rm -rf /var/tmp/postgresql-17-202405161
rm: cannot remove '/var/tmp/postgresql-17-202405161/bin/pg_resetwal': Permission denied
rm: cannot remove '/var/tmp/postgresql-17-202405161/bin/pg_walsummary': Permission denied
...
rm: cannot remove '/var/tmp/postgresql-17-202405161/lib/plpgsql.so': Permission denied

I needed an account with sudo to wipe that directory out:
sudo rm -rf /var/tmp/postgresql-17-202405161

Not sure how you want to deal with this, seems like a rough edge that should be polished before release.
