How to Install Aegisub Subtitle Editor on Ubuntu 18.10 and 19.04

Aegisub is the industry-standard open-source tool for creating, styling, and timing Advanced SubStation Alpha (.ass) subtitles. When Ubuntu temporarily removed Aegisub from official distribution archives in versions 18.10 and 19.04, users could maintain full access via the verified Anton multimedia PPA repository.
