Public bug reported: I assume that you decided for uniform distribution in the random number generator. If group of dependent packages is installed only when all phased-update-percentage values (for each package) are smaller than the present percentage on server - it will change probability distribution for the whole group of packages.
Just run this: figure(1) hist(rand(1,100000)) for i = 2:10 figure(i) hist(max(rand(i,100000))) endfor in octave and look at histograms for i>1 (i is the number of dependent packages). ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1214482 Title: Not-grouping dependent packages in Phased Updates changes propability distribution for entire group of dependent packages.
