I can reproduce this in testing:
| # apt-get install sugar-moon-activity
…
| The following packages have unmet dependencies:
|  sugar-moon-activity : Depends: python-sugar-0.86 but it is not installable or
|                                 python-sugar-0.88 but it is not going to be installed
|                        Depends: python-sugar-toolkit-0.86 but it is not installable or
|                                 python-sugar-toolkit-0.88 but it is not going to be installed
| E: Unable to correct problems, you have held broken packages.

but specifying python-sugar-0.88 and python-sugar-toolkit-0.88 on the
apt-get install command line makes apt find a solution:
| # apt-get install python-sugar-0.88 python-sugar-toolkit-0.88 sugar-moon-activity
…
| 0 upgraded, 410 newly installed, 0 to remove and 0 not upgraded.

Adding apt folks to the loop for possible input, and downgrading
severity to important since it's actually possible to find a solution
even if one has to specify it manually.
