As per this link Noticed that PPA support is available till Ubuntu-16.10.

Our PPA supports Ubuntu 16.10, 16.04, 15.10, 14.04 and 12.04 as well as Linux Mint 18, 17.x and 13. Add the PPA and install Oracle Java 8 (the package provides both JDK8 and JRE8) using the following commands:

Is there any workaround to install oracle JDK-1.8 on Ubuntu-20.04-LTS docker?

It seems that you blindly adding some PPA to your Dockerfile. This Oracle Java (JDK) 8 Installer PPA (DISCONTINUED) does not provide packages for 20.04 LTS (focal) - see http://ppa.launchpad.net/webupd8team/java/ubuntu/dists/ , also it is now marked as discontinued by its owners.

You have to replace this PPA by some other, for example this “Hellenic Schools Technical Support Team” team PPA provides needed package for Ubuntu 20.04 LTS .

So you have to put the following line into Dockerfile:

add-apt-repository ppa:ts.sch.gr/ppa

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
