Hello, I confirm the "bug" which is also on my system.
Yet, this occurs only because the package requisites miss 'gir1.2-tsparql-3.0' (as stated in the error message).
A quick workaround: #> sudo aptitude install gir1.2-tsparql-3.0 But, the package maintainer should add a new dependency to gir1.2-tsparql-3.0. Regards -- Emmanuel Fleury
