Got this error while sudo apt update

Err:8 http://in.archive.ubuntu.com/ubuntu bionic InRelease                             
  Cannot initiate the connection to in.archive.ubuntu.com:80 (2403:8940:ffff::f). - connect (101: Network is unreachable) Could not connect to in.archive.ubuntu.com:80 (103.97.84.254), connection timed out


Searching I found that there may be problem resolving IPv6 address. So, forced IPv4 using sudo apt -o Acquire::ForceIPv4=true update, even though as we see above apt tries IPv4.

Err:8 http://in.archive.ubuntu.com/ubuntu bionic InRelease                                             
  Could not connect to in.archive.ubuntu.com:80 (103.97.84.254), connection timed out


To make sure problem is not caused by other ppa, I reset my /etc/apt/sources.list from http://repogen.simplylinux.ch/. Still doesn't solve the problem.

Also tried changing mirror. Error persists

Finally I tried to see debug info using sudo apt -oDebug::pkgAcquire::Worker=1 update, but output doesn't give extra info

I also tried removing DNS cache using sudo systemd-resolve --flush-caches

Comments

I cropped debug output to remove unnecessary output, but I can edit to post full output.

I mostly found issue was with DNS in other questions, but I am able to ping servers so that shouldn't be a problem.

Question

Is there a way I can fix this? If not, is there a way to reset DNS+apt+sources so that everything works(apart from reinstall ubuntu)?

Edit: Also, when I reset sources.list, I still see extra ppa like steam ppa, kritalime ppa, etc... Did I do miss something after writing sources.list ?

As there was a problem with connecting in.archive.ubuntu.com itself, I solved it by changing all the URLs to working mirror.

/etc/apt/sources.list
