Cannot install extentions via cli when apache2 is installed

[danielraab]

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: does not matter -> cli problem
• Local OS: does not matter -> cli problem
• Remote OS: docker image codercom/enterprise-base:ubuntu
• Remote Architecture: x86
• code-server --version: 4.103.1 fbaadbc with Code 1.103.1

Steps to Reproduce

1. create template from docker template (without changes)
2. create workspace with created template
3. start workspace
4. start terminal of workspace
5. install and start apache2 sudo apt update && sudo apt install apache2 && sudo apache2ctl start
6. try to install a code-server extensions via cli: /tmp/code-server/bin/code-server --force --install-extension dracula-theme.theme-dracula

Expected

the extension installation should work. It works with stopped apache2

Actual

the extension can not be installed. The extention is not found:

Extension 'dracula-theme.theme-dracula' not found.
Make sure you use the full extension ID, including the publisher, e.g.: ms-dotnettools.csharp
