Bug Description
I assume that you decided for uniform distribution in the random number generator. If group of dependent packages is installed only when all phased-
Just run this:
figure(1)
hist(rand(
for i = 2:10
figure(i)
hist(max(
endfor
in octave and look at histograms for i>1 (i is the number of dependent packages).
To post a comment you must log in.
For normalized histograms:
figure(1) 1,100000) ,10,1) rand(i, 100000) ),10,1)
hist(rand(
for i = 2:10
figure(i)
hist(max(
endfor
If we're upgrading kernel, than packages are: generic version version- generic version- generic
linux-generic
linux-headers-
linux-image-generic
linux-libc-dev
linux-headers-
linux-headers-
linux-image-
so for this group i=7 and for percentage < 40% will be almost no bug reports ;)
