@Reggie,

I’ve updated the instructions regarding the CentOS-Base.repo file due to CentOS 7’s end of life.

1. Uncomment the lines starting with baseurl.
2. Replace all instances of http://mirrorlist.centos.org with http://vault.centos.org.
3. Replace all instances of http://mirror.centos.org with http://vault.centos.org.

After making these changes, run:

sudo yum update -y

@Arc,

Here’s the step-by-step process for executing the commands you’ve provided:

1. Navigate to the ‘/etc/yum.repos.d‘ directory:

cd /etc/yum.repos.d

2. Rename all files except ‘CentOS-Base.repo‘ to include the suffix ‘-oldfilename‘:

for file in *; do
       if [ "$file" != "CentOS-Base.repo" ]; then
           mv "$file" "${file}-oldfilename"
       fi
   done

3. Copy ‘CentOS-Base.repo` to ‘CentOS-Base.repo-‘:

cp CentOS-Base.repo CentOS-Base.repo-

4. Modify ‘CentOS-Base.repo‘ to replace ‘$releasever‘ with `7`:

sed -i 's/$releasever/7/g' CentOS-Base.repo

5. Update the repositories using ‘yum‘:

yum update

6. If Linux recovered some files with a '-' suffix during step 2, rename them back:

   for file in *; do
       if [[ "$file" == *-oldfilename ]]; then
           new_file=$(echo "$file" | sed 's/-oldfilename//')
           mv "$file" "$new_file"
       fi
   done

7. Modify ‘CentOS-Base.repo‘ again to replace ‘7‘ with ‘$releasever‘:

sed -i 's/7/$releasever/g' CentOS-Base.repo

8. Run ‘yum update‘ again:

yum update

This script will execute the steps you’ve outlined, ensuring that the repository files are managed and updated as specified. Make sure to review the changes carefully before executing each command to avoid any unintended consequences.

Hi
Please full write command line ….

That helped me. Thank you…
