TL;DR

• The issue may be resolved by setting the required environment variable GITHUB_PERSONAL_ACCESS_TOKEN to prevent plugin MCP server errors.

Guidance

• Check if the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is set before running the claude CLI.
• Verify that the lock acquisition failure is not causing the freeze by checking the file system permissions for /home/jshute/.local/share/claude/versions/2.1.104.
• Try setting the GITHUB_PERSONAL_ACCESS_TOKEN environment variable and then run the /config command again to see if it resolves the issue.
• If the issue persists, investigate the lock acquisition failure error further to determine if it's related to the freeze.

Example

• To set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable, you can use the command export GITHUB_PERSONAL_ACCESS_TOKEN=your_token_value before running the claude CLI.

Notes

• The provided error messages suggest that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is missing, which may be causing the plugin MCP server errors.
• The lock acquisition failure error may be a separate issue, and further investigation is needed to determine its cause.

Recommendation

• Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to prevent plugin MCP server errors, as this is the most likely cause of the issue based on the provided error messages.
