I am trying to install this extension by following the instructions and am getting an error.

git clone https://github.com/citusdata/postgresql-hll.git tar cvfz postgresql11-hll-2.12.tar.gz postgresql-hll --transform="s/postgresql-hll/postgresql11-hll/g" rpmbuild -tb postgresql11-hll-2.12.tar.gz error: Failed to read spec file from postgresql11-hll-2.12.tar.gz

I get the same error today:

rpmbuild -tb postgresql${PGSHRT}-hll-${VER}.tar.gz error: Failed to read spec file from postgresql11-hll-2.12.tar.gz

You can use the binaries from:

https://yum.postgresql.org/

assume these binaries won't work for ubuntu?
