I am currently using Ubuntu 18.04, and I need gcc 4.8 for MATLAB. So I tried to install gcc-4.8 using
$ sudo apt-get install gcc-4.8
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-libc-dev_4.15.0-117.118_amd64.deb 404 Not Found [IP: 2403:8940:3:1::f 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
so I ran the command
sudo apt-get update
I didn't show any error but running gcc version command gave this
$ gcc -v
Command 'gcc' not found, but can be installed with:
sudo apt install gcc
previously I used to have 7.5 but now it is not.
sudo apt-get --purge remove gcc i tried by giving verion at end but it didnt work

(which removes gcc 7.5 in 18.04) 2. You can change the default gcc version by using theupdate-alternatives
command to determine which actual file is referenced by a generic name, for example which actual file is referenced bygcc
. For more information see the answers to this question: How to change the default GCC compiler in Ubuntu?. – karel Sep 28 '20 at 07:14
