Unable to download package successfully after apt install

I tried to install Firefox for scraping on Ubuntu 18.04 that I installed from mini.iso, but it failed.
What should I do?

$sudo apt install Firefox-y

Other environments and things to check:

I don't use a proxy
I have verified that the URL and IP address in the message are pinged.
When I changed the package source from Toyama University to JAIST, the result was similar.
I also tried apt clean and apt update beforehand, but the installation fails.

As I answered myself, the installation from the file was successful, but this time I can no longer do apt upgrade.Originally, it was successful without any problems.

I tried apt install again on 2020-08-03, but it failed as well.

Instead, I succeeded in installing the file that I got from wget in the following steps, starting in headless mode or operating from Selenium in Python.
Therefore, I have achieved my goal.

$sudoapt install./firefox_79.0+build1-0ubuntu 0.20.04.1_amd64.deb
