[Dragos Jarca]

Ok, I upgraded to experimental and after some isues, it finally work.

The problems:
1. sprockets:
NameError: uninitialized constant Bundler

resolved with delete of .bundle/cache

2. rugged
/var/lib/gems/2.5.0/gems/rugged-0.26.3/lib/rugged.rb:10:in `require': 
/usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not 
found (required by 
/var/lib/gems/2.5.0/gems/rugged-0.26.3/lib/rugged/rugged.so) - 
/var/lib/gems/2.5.0/gems/rugged-0.26.3/lib/rugged/rugged.so (LoadError)

resolved using rugged-0.27 from experimental
