Hi Alex, > I looked on some other python3 packages and for example I get a similar > result for python-dnsq package Are you building on sid? Seems like you would need to build on experimental to get python3.4: https://packages.debian.org/sid/python3 has 3.3.4-1 https://packages.debian.org/experimental/python3 has 3.4~rc1-1 Cheers! Daniel
