How to silence the commit function from the python apt library?

Question

I use python apt library and I would like that the commit() function doesn't produce any output.

I've searched on the web and saw that the fork function can do the trick but I don't know how to do that or if there exists another way. I don't use any GUI, I work via the terminal.

The easiest solution is probably to use something like:

class LogInstallProgress(apt.progress.base.InstallProgress):
    def fork(self):
        pid = os.fork()
        if pid == 0:
            logfd = os.open("dpkg.log", os.O_RDWR | os.O_APPEND | os.O_CREAT, 0o644)
            os.dup2(logfd, 1)
            os.dup2(logfd, 2)
        return pid

and then in commit():

 cache.commit(install_progress=LogInstallProgress())

But be careful, note that deb packages may do conffile prompts and similar things, so you will want to override conffile() (and error too).
