How to find out how a program was removed?

  • 772

Is there a way to see how a program was removed? In this case I had telegram installed on ubuntu 16.04 and now its not there, running

cat /var/log/apt/history.log | grep telegram

did not return any results. Possibly I agreed to remove it when installing another package but I wanted to confirm if that was the case and if not why it happened. Im not certain but I think it was originally installed by running

sudo apt-get install telegram

16.04

  1. Your apt/history.log gets rotated and archived, meaning roughly every month the logfile gets compressed and stored as /var/log/apt/history.log.X.gz, where X is an incrementing number, 1 being the newest archive.

    To also search the older, compressed archives for the string telegram, you can use zgrep which is capable of automatically uncompressing files before matching, if needed:

    zgrep telegram /var/log/apt/history.log*
