01:40:05 Some packages could not be installed. This may mean that you have
01:40:05 requested an impossible situation or if you are using the unstable
01:40:05 distribution that some required packages have not yet been created
01:40:05 or been moved out of Incoming.
01:40:05 The following information may help to resolve the situation:
01:40:05
01:40:05 The following packages have unmet dependencies:
01:40:05 sbuild-build-depends-dose3-dummy : Depends: dose-distcheck but it is not installable
01:40:05 E: Unable to correct problems, you have held broken packages.
01:40:05 apt-get failed.
01:40:05 E: Package installation failed

I don't know how to fix this issue.
If it's not a trivial fix, please move this ticket into Core Tor/Tor, and someone should deal with it soon.
