And I am not able to install php 7.4 after this using sudo apt-get install php7.4
My question is how to install php 7.4 on this version of Ubuntu?
You have to wait until packages for this new Ubuntu version are released in OndrejSury repository.
https://launchpad.net/~ondrej/+archive/ubuntu/php?field.series_filter=
If you look now he currently supports versions 18.04 (bionic), 20.04 (focal) and 21.04 (hirsute).
When he will add packages for 21.10 (impish), then you will be able to add this repository.
