I have never used bleachbit, but I took a look at this program to see if
it would be a simple matter to convert it to python3. It won't.
As I wrote in another e-mail, upstream is working to port the program to python3. There is a related branch on github.
Sorry but by mentioning a retired package, and the possibility to package it again in Fedora once upstream will release a python3 version, it was not my intention to trigger a discussion about python2 policies and procedures that, as far as I know, they were pretty clear since a lot of time.
