Release 3.5.1 (#218)

* chore: bless 3.5.1

* fix(debian): there is an unexpected empty line in template

* fix: make sure we can install the package

We notice that the package was broken only when installing. Apparently, the
debian script do not check for errors during the build.

* fix(debian): nice that the build breaks now let's see if it fixes
