Ubuntu 19.04 trouble running apt update

Question

I am trying to install phpmyadmin in Ubuntu 19.04 and got myself in the following trouble. Can anyone help me with it?

My question is different from all the questions some guys are referring to. I am not sure where they found similarity but by looking at their question my question is certainly different.

I'd suggest switching mirrors; I didn't work out which it is on https://launchpad.net/ubuntu/+archivemirrors it is (ie. is it maintained well, or last-update so far gone it's counter-overflowed (thus unknown), but I'm getting errors on it too [University of Science and Technology of China, in browser] — guiverc, Jul 30 '19 at 06:47
@beingadityak I have added the output of this command in my question. — Curious Developer, Jul 30 '19 at 07:40
@guiverc I am also sure that I need to switch those mirror links. As they are not working now. But I am not sure how to do it and which links to replace with. — Curious Developer, Jul 30 '19 at 07:42

@fkraiem It doesn't look like a duplicate as the issue for the OP is with the mirrors' URL — beingadityak, Jul 30 '19 at 07:45
To change mirror, please refer to https://help.ubuntu.com/community/Repositories/Ubuntu (Download Server section, the picture will look somewhat like the image just under CD-ROM/DVD title in the "Download from:") — guiverc, Jul 30 '19 at 07:51

I found that my sources.list had some source links that were no longer exists. They were added during my attempt to install other software. So when every time I was trying to run an update system wasn't able to fetch the necessary packages.

I was able to resolve the issue using the answer on this post by replacing the sources list

Now, my issue is fixed and I am able to install the other software.
