Let’s get ready with the right tips to solve the “User Interaction is Not Allowed” error easily!

Part 1 - Verify Jenkins Configuration for Non-Interactive Execution

We need to fix the “User Interaction is Not Allowed” error when signing an OSX app with Codesign in Jenkins. To do this, we should make sure Jenkins is set up for non-interactive execution. Here are the steps:

  1. Configure Jenkins to run as a User with GUI Access:

    • We must check that Jenkins runs under a user account that can access the GUI session. This is very important. It helps the codesigning process work with the Keychain.

  2. Set Up Jenkins Environment:

    • We need to change the environment variables in our Jenkins job:

      export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer"
export CODE_SIGN_IDENTITY="Your Code Signing Identity"

  3. Use the Jenkins Agent:

    • If we are using a Jenkins agent, we have to make sure it is on a machine with a GUI. This is also important for the codesigning process.

  4. Adjust Jenkins Job Configuration:

    • In our job settings, we should select the right build environment that allows GUI access:
      • Under Build Environment, we need to check “Run the build in a Docker container” if we use it. But we must make sure the container has GUI access.

  5. Scripts for Non-Interactive Code Signing:

    • We should change our signing script to add the --deep and --force flags with codesign:

      codesign --force --deep --sign "Your Code Signing Identity" /path/to/your.app

  6. Frequent Updates:

    • We need to keep Jenkins and its plugins updated. This helps to avoid problems that might cause user interaction errors.

By making sure our Jenkins setup allows for non-interactive execution and has the right environment, we can fix the “User Interaction is Not Allowed” error when signing our OSX app. For more details on Jenkins configurations, we can check this Jenkins Pipeline Guide.

Part 2 - Use the -f Flag with Codesign

To fix the “User Interaction is Not Allowed” error when we sign an OSX app with Codesign in Jenkins, we can use the -f flag. This flag makes the code signing process replace existing signatures without asking for user input.

Here is how we can do it:

  1. In our Jenkins pipeline or shell script, we need to change our Codesign command to add the -f flag.
codesign -f -s "Developer ID Application: Your Name (Team ID)" /path/to/YourApp.app
  1. We should replace "Developer ID Application: Your Name (Team ID)" with our real signing identity. We also need to change /path/to/YourApp.app to the right path of our application.

By using the -f flag, we can skip the prompts that cause the “User Interaction is Not Allowed” error. For more information about fixing Jenkins pipeline problems, look at this link.

Part 3 - Ensure Correct Keychain Access Settings

To fix the “User Interaction is Not Allowed” error when we sign an OSX app with Codesign in Jenkins, we must check our keychain access settings.

  1. Keychain Access: First, we open Keychain Access on our Mac. We need to find the certificate we use for signing. We must make sure it allows access to the Jenkins user.

  2. Access Control:

    • We right-click on the certificate and pick “Get Info”.
    • Then, we go to the “Access Control” tab. Here, we check that “Allow all applications to access this item” is selected. If we want to limit access, we can add the Jenkins application.

  3. Keychain Unlock: We have to unlock the keychain before the Jenkins job runs. We can do this by adding a step in our Jenkins pipeline to unlock the keychain:

    security unlock-keychain -p <your_keychain_password> /Users/<your_username>/Library/Keychains/login.keychain-db

  4. Keychain Path: We should check that Jenkins uses the right keychain. We can specify the keychain in our Codesign command:

    codesign --keychain /Users/<your_username>/Library/Keychains/login.keychain-db -s "<Certificate Name>" <path_to_your_app>

  5. Environment Variables: If Jenkins runs as a service, it may not have access to the user’s keychain. We need to set the environment variables correctly in Jenkins to point to the right keychain.

By making sure the keychain access settings are correct, we can avoid the “User Interaction is Not Allowed” issue when signing in Jenkins. For more help, we can check how to fix missing certificates or look into Jenkins pipeline configurations.

Part 4 - Update Jenkins to the Latest Version

We can fix many issues by updating Jenkins to the latest version. This includes the “User Interaction is Not Allowed” error that happens when we sign an OSX app with Codesign. Let’s follow these steps to keep our Jenkins up to date:

  1. Backup Your Jenkins Configuration:

    cp -R /var/lib/jenkins /var/lib/jenkins_backup

  2. Update Jenkins:

    • For Debian-based systems like Ubuntu:

      sudo apt-get update
sudo apt-get install jenkins

    • For Red Hat-based systems like CentOS:

      sudo yum update jenkins

    • For macOS using Homebrew:

      brew update
brew upgrade jenkins-lts

  3. Verify the Update: After we update, we should check the version we have installed:

    java -jar /usr/share/jenkins/jenkins.war --version

  4. Restart Jenkins:

    • For Debian-based systems:

      sudo systemctl restart jenkins

    • For Red Hat-based systems:

      sudo systemctl restart jenkins

    • For macOS:

      brew services restart jenkins-lts

  5. Check for Plugin Updates: We should go to Manage Jenkins then Manage Plugins. Here we make sure all plugins are up to date. This helps to keep everything working well with the latest Jenkins version.

Updating Jenkins can help with issues related to code signing in our Jenkins builds. If we still have problems, we might want to check our Jenkins settings for non-interactive execution. We can find more about this in Part 1 - Verify Jenkins Configuration for Non-Interactive Execution. Also, we can think about using a dedicated build agent for signing. More info is in Part 6 - Use a Dedicated Build Agent for Signing.

Part 5 - Check for Missing Entitlements in the App

To fix the “User Interaction is Not Allowed” error when signing your macOS app with Codesign in Jenkins, we need to check that the app has the right entitlements. If entitlements are missing, it can stop the app from being signed well.

  1. Verify Entitlements File: We should make sure your app’s entitlements file is set up correctly. This file needs to have the right keys for what the app should do.

    Here is an example of a simple entitlements file (MyApp.entitlements):

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.security.app-sandbox</key>
    <true/>
    <key>com.apple.security.network.client</key>
    <true/>
    <key>com.apple.security.network.server</key>
    <true/>
</dict>
</plist>

  2. Check the Signing Command: We need to make sure we are using the entitlements file right in our codesign command in Jenkins.

    Here is an example command:

    codesign --deep --force --verify --verbose --sign "Developer ID Application: Your Name (Team ID)" --entitlements MyApp.entitlements /path/to/MyApp.app

  3. Review App Capabilities: In Xcode, we should check that the app’s capabilities are turned on as needed. Go to the “Signing & Capabilities” tab. Make sure the needed features are on.

  4. Validate Entitlements: We can use the codesign command to check that the entitlements are in the app after signing:

    codesign -d --entitlements :- /path/to/MyApp.app

    This command will show the entitlements that are in the app. We need to make sure they are what we expect.

Part 6 - Use a Dedicated Build Agent for Signing

To fix the “User Interaction is Not Allowed” error when we sign an OSX app with Codesign in Jenkins, we should use a special build agent made just for signing. This method keeps the signing process separate. It helps us avoid problems from other builds or jobs.

  1. Set Up a Dedicated Build Agent:

    • First, we need to create a new Jenkins agent (node). This agent will only handle the signing.
    • We must make sure this agent runs on a machine that has the signing certificates and provisioning profiles already installed.

  2. Configure the Build Agent:

    • Next, we install Xcode and the needed command-line tools on the agent.
    • Also, we check that the codesign tool is available.

  3. Adjust Jenkins Node Settings:

    • In Jenkins, we go to “Manage Jenkins” then “Manage Nodes and Clouds”.
    • We find our dedicated build agent and set it up to use special labels that show what it does, like signing-agent.

  4. Use the Dedicated Agent in Your Pipeline:

    • In our Jenkins pipeline script, we need to say which agent to use for the signing step:
    pipeline {
    agent none
    stages {
        stage('Build') {
            agent { label 'linux' }
            steps {
                // Build steps here
            }
        }
        stage('Sign') {
            agent { label 'signing-agent' }
            steps {
                sh 'codesign --deep --force --verify --verbose --sign "Developer ID Application: Your Name (Team ID)" /path/to/your/app'
            }
        }
    }
}

  5. Keychain Access:

    • We should make sure the keychain we use for signing is unlocked and can be reached by the Jenkins agent. We might need to use the security command to unlock the keychain before we sign:
    security unlock-keychain -p your_password /path/to/your/keychain

By using a dedicated build agent for signing, we can make the process easier and reduce user interaction problems. This way, we improve the reliability of our CI/CD pipeline. If we want to know more about how to configure Jenkins agents, we can check this Jenkins CI setup guide.

Frequently Asked Questions

1. What causes the “User Interaction is Not Allowed” error when signing an OSX app with Codesign in Jenkins?

The “User Interaction is Not Allowed” error usually happens when we try to sign an OSX app in Jenkins without the right permissions or an interactive session. This can occur if we run Jenkins as a service that does not have access to the GUI. It can also happen if we do not set up the Codesign command correctly. For more help, see our guide on fixing missing certificates.

2. How can I configure Jenkins for non-interactive execution to avoid signing issues?

To set up Jenkins for non-interactive execution, we need to make sure the Jenkins user has the right permissions to access the keychain. We also have to set up the build agent to run without needing user interaction. You can look at our detailed article on how to access the build environment for more specific steps.

3. Why should I use the -f flag with Codesign during app signing?

When we use the -f flag with the Codesign command, it forces the signing to continue even if the app is already signed. This is useful in automated places like Jenkins where we may need to change previous signatures. For more details, see our article on how to fix Jenkins CI pipeline issues.

4. What are the keychain access settings necessary for signing OSX apps in Jenkins?

Good keychain access settings are very important for signing OSX apps in Jenkins. We need to check that the Jenkins user can access the right certificates in the keychain. Also, the keychain should be unlocked during the build process. If we have problems, our guide on fixing Jenkins host key problems might give us more solutions.

5. How can I ensure my Jenkins build agent is properly set up for app signing?

To make sure our Jenkins build agent is set up right for app signing, we should use a dedicated build agent. This agent needs to have all the tools and permissions ready. It should access the keychain without user interaction and have the correct environment variables set. For more help, check our article on how to set up Jenkins CI with Docker.
