Dockerfile error when running apt-get install

  apache, apache2, apt-get, docker

Im new to docker and tried a few different setups in my Dockerfile and it works great. Now when I try to use apt-get install inside my docker file (docker build .) it just breaks and I get the following error:

=> ERROR [ 6/14] RUN apt-get install -y php8.0-gd
 > [ 6/14] RUN apt-get install -y php8.0-gd:

#11 0.846 E: Couldn't find any package by glob 'php8.0-gd'
#11 0.846 E: Couldn't find any package by regex 'php8.0-gd'

I’ve tried to change to other apt-get install packages but same result no matter what package I try to install. I’ve also tried to install all packages in one RUN command, bud rewrote the code as shown below, to see if it was one specific package that crashed it.

Here is my code:

FROM php:8.0-apache-buster

RUN mkdir /workdir

WORKDIR /workdir

COPY . .

RUN apt-get update -y
RUN apt-get install -y php8.0-gd
RUN apt-get install -y php8.0-imagick
RUN apt-get install -y php8.0-pgsql
RUN apt-get install -y php-gettext
RUN apt-get install -y php8.0-curl
RUN apt-get install -y php8.0-soap
RUN apt-get install -y php-bcmath
RUN apt-get install -y language-pack-ko-base
RUN a2enmod rewrite


CMD ["/usr/sbin/apache2ctl","-DFOREGROUND"]

I’ve searched and search but cannot find someone with the same problem. I am really new to Docker and I havn’t figgured out if it is better to set this up in the docker-composer.yml file?
