Can't install GCC in Ubuntu 20.04 WSL

I have tried to install gcc in Ubuntu 20.04 on WSL :

apt -y install gcc return error:

Reading package lists... DoneBuilding dependency treeReading state information... Donegcc is already the newest version (4:9.3.0-1ubuntu2).0 upgraded, 0 newly installed, 0 to remove and 194 not upgraded.1 not fully installed or removed.After this operation, 0 B of additional disk space will be used.Setting up gcc (4:9.3.0-1ubuntu2) ...update-alternatives: error: alternative path /usr/bin/gcc doesn't existdpkg: error processing package gcc (--configure): installed gcc package post-installation script subprocess returned error exit status 2Errors were encountered while processing: gccE: Sub-process /usr/bin/dpkg returned an error code (1)

I tried to fix it with :

sudo dpkg --purge --force-depends gcc sudo apt-get autoremove -ysudo apt-get autoclean -ysudo apt-get clean gccsudo apt-get install gcc

But then I got error :

How can I install gcc in my Ubuntu?
