I use certbot a lot. I discovered a bug and logged it on github and got this back from the developer

and now this…
Yesterday I installed ubuntu 20 and virtualmin and certbot 3 times. The problem was using SNAP to install certbot - the boot time went to over 3 mins - I was following the instructions on the certbot site
which advises to use snap. On the 3rd reimage I installed certbot from ubuntu and boot time is now 45 seconds.
