Problem

When installing Terraform Enterprise (TFE) Replicated using this article , on RHEL 7.9 with SELinux enabled, customers may encounter an issue while running yum install yum-utils. The error message observed is:

Loaded plugins: langpacks, product-id, search-disabled-repos, versionlock, yum_rhui_plugin
https://rpm.releases.hashicorp.com/RHEL/7Server/x86_64/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.

This error prevents the installation from proceeding and is related to a repository configuration issue.

Prerequisites

Installing TFE replicated on RHEL7.9

Note - You may face similar issue in other RHEL7 versions as well

Cause

1 -: RHEL 7.9 has reached its End of Maintenance (EoM) phase. You can find more details about it [here].The HashiCorp repository does not provide packages for distributions that have reached their end-of-life status.

2-: The issue occurs because the $releasever variable in the base URL for the HashiCorp repository does not resolve correctly in certain RHEL 7.9 environments. The variable $releasever translates to 7Server instead of 7, leading to an invalid URL.

For example, the repository URL is set to:

https://rpm.releases.hashicorp.com/RHEL/7Server/x86_64/stable

This URL results in a 404 error because 7Server is not a valid directory on the repository server.

Possible Solution

Note: RHEL 7.9 has reached its End of Maintenance (EoM) phase, and it is not recommended to continue using this operating system. However, if its use is necessary for specific cases, the following workaround can be applied to address the issue.

Solution 1: Static Base URL Update

After running the command:sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

A repository file is created under /etc/yum.repos.d/. Inside this file, in the baseurl field for the HashiCorp repository, you need to replace the variable $releasever with the static value 7. This ensures that the packages resolve correctly.

Open the repository configuration file:
```
sudo vi /etc/yum.repos.d/hashicorp.repo
```

Locate the baseurl line. It will look similar to:

baseurl=https://rpm.releases.hashicorp.com/RHEL/$releasever/x86_64/stable

Replace $releasever with 7 to create a static URL. The updated line should be:
```
baseurl=https://rpm.releases.hashicorp.com/RHEL/7/x86_64/stable
```
Save the file and exit the editor.
Run the command "yum clean all"
Retry the installation:
```
sudo yum install yum-utils
```

This ensures that the repository URL resolves correctly.

Solution 2: Temporarily Disable the Repository (Only if solution 1 is not working )

Open the HashiCorp repository configuration file:
```
sudo vi /etc/yum.repos.d/hashicorp.repo
```
Locate the enabled parameter and change its value from 1 to 0 to disable the repository:
```
enabled=0
```
Save the file and exit the editor.
Proceed with the required installation using an alternative or already-configured repository:
```
yum install yum-utils
```
Once the installation is complete, re-enable the HashiCorp repository by setting the enabled parameter back to 1:
```
enabled=1
```
Save the changes and exit the editor.

Outcome

By following the recommended solution outlined above, you should be able to successfully install TFE Replicated. However, if the issue persists, please open a support ticket with HashiCorp for further assistance.
