Downgrading to GCC 7.3.0 from 7.4.0 in ubuntu 18.04 environment

[RAJ PRAJAPATI]

Hello Team,

First of all, thanks very much for bringing up such software to the world!

I am little bit stuck and need support.

Currently I am having GCC version 7.4.0.(previously some days before it was
7.3.0)

However I wanted to have only 7.3.0. I am not sure on how it got updated to
7.4.0 but my requirement is to install specifically 7.3.0.

I am using ubuntu 18.04.

Even after removing gcc entirely, not able to install 7.3.0.

It would be really helpful to know how to successfully downgrade from 7.4.0
to 7.3.0 Or to completely remove the 7.4.0 and freshly install 7.3.0.

If possible, kindly share the commands, it would be really appreciable.

Thanks And Regards,

Raj Prajapati
