In /var/log/apt, I am seeing:

It looks like history.log is being archived once a month.

Because history.log and its archives are important to me, I want to know:

• how many archives will be stored before the oldest is deleted?


• where is this information located?


• can I change the settings to increase the number of logs stored? (Going from the file sizes and my usage of apt-get, I am not concerned about disk space.)

Thank you.
