I want to uninstall my gcc by terminal. When I type
gcc --version
The output is
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

Could anyone help me? How can I install the last version of gcc after that?
回答1:
Use the following command (Replace <version> with the appropriate version):
sudo apt-get --purge remove gcc-<version>
You can install a specific version of a program using apt, you can use the following command. (Replace <version> with the appropriate version)
sudo apt-get install gcc=<version>
Alternatively, you can use Synaptic Package Manager.
sudo apt-get update
sudo apt-get install synaptic
Note that, you might need GCC for some programs. If you face any driver issues while installing programs / drivers you can install the latest GCC by using:
sudo apt-get install gcc
