+Description: Remove hardcoded tlsv1 protocol version
+ The test-suite of libprotocol-http2-perl uses a hardcoded value of tlsv1 -
+ which is disabled in Ubuntu by means of OpenSSL seclevel. Specifying another
+ version like tlsv1_2 would work but it seems sensible to leave that up to the
+ system decide.
