Unable to fetch some archives, maybe run apt-get update using Mobaxterm - apt

Question

I downloaded Mobaxterm to use the a Bash shell. The problem is, I can't compile my C files with "cc -o file file.c". It shows me this :
Command 'cc' not found, but can be installed with:
sudo apt install gcc
sudo apt install clang
sudo apt install pentium-builder
sudo apt install tcc
But whenever I type these commands it returns me error messages such as :
Ign:1 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 linux-libc-dev

Answer 1

Go to Plugin section of the website and download plugin
Gcc, G++ and development tools: the GNU C/C++ compiler and other development tools.
It'll download a file named Development.mxt3
Now go to C:\Program Files (x86)\Mobatek\MobaXterm\ folder and paste the downloaded file here.
Copying the plugin file here
Open the application's terminal and by now you'll be able to compile
cc -o file file.c
and run as follows
./file.exe
compile & run
