Solving the CURL 77 Error When Installing AApanel on Rocky Linux 9.3 Minimal

If you’re reading this, chances are you’re stuck with the frustrating CURL 77 error when trying to install AApanel on Rocky Linux 9.3 Minimal. Don’t worry, you’re not alone! This article will guide you through the troubleshooting process and provide a step-by-step solution to get AApanel up and running smoothly.

Understanding the CURL 77 Error

The CURL 77 error is a common issue that occurs when the CURL library, which is used for transferring data, encounters a problem. In the context of AApanel installation, this error typically indicates that there’s an issue with the SSL/TLS certificate verification process.

What Causes the CURL 77 Error?

The CURL 77 error can be triggered by various factors, including:

• SSL/TLS certificate issues: Expired, invalid, or self-signed certificates can cause CURL to fail.
• Firewall or network configuration problems: Firewalls or strict network settings can block CURL requests.
• Outdated or corrupted CURL version: Using an outdated or corrupted CURL version can lead to errors.
• Repository or package manager issues: Problems with the repository or package manager can prevent AApanel from installing correctly.

Step-by-Step Solution to Fix the CURL 77 Error

To resolve the CURL 77 error, follow these steps in the order presented:

Step 1: Update the System and Install Required Packages

sudo dnf update -y
sudo dnf install epel-release -y
sudo dnf install curl -y
sudo dnf install openssl -y
sudo dnf install ca-certificates -y

This step ensures that your system is up-to-date and has the necessary packages installed, including CURL and OpenSSL.

Step 2: Verify SSL/TLS Certificate Configuration

Create a new file /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem using the following command:

sudo update-ca-trust

This command updates the system’s certificate trust store and extracts the TLS/SSL certificates.

Step 3: Configure the Firewall

Allow outgoing traffic on port 443 (HTTPS) to enable CURL to communicate with the repository:

sudo firewall-cmd --permanent --add-rule ipv4 output 443 -j ACCEPT
sudo firewall-cmd --reload

This step ensures that the firewall is not blocking CURL requests.

Step 4: Update the AApanel Repository

Update the AApanel repository to ensure you have the latest package information:

sudo dnf update -y
sudo dnf install aapanel -y

Step 5: Verify CURL Version

Check the CURL version to ensure it’s up-to-date:

curl -V

If you’re using an outdated version, update CURL using the following command:

sudo dnf install curl -y

Step 6: Reinstall AApanel

Reinstall AApanel to complete the installation process:

sudo aapanel install

After completing these steps, you should be able to install AApanel successfully without encountering the CURL 77 error.

Troubleshooting Tips and Variations

If you still encounter issues, try the following troubleshooting steps:

• Disable SELinux: Temporarily disable SELinux to see if it’s interfering with the installation process:

  sudo setenforce 0

• Check system logs: Review system logs to identify any specific error messages that might indicate the cause of the issue:

  sudo journalctl -u aapanel

• Verify network connectivity: Ensure that your system has a stable internet connection:

  ping google.com
