I used to compile c code in my linux machine but it always showed there is problem with my gcc. I gcc changed versions but it didn’t help. So i thought of removing /usr/bin/gcc and its rappers and reinstall it. Now i am unable to reinstall it.

I tried many ways to reinstall but it always shown below error.
