Getting an ambiguous error while trying to set my local server as VPN server

[isacikgoz]

Describe the bug

I am getting a failure at the TASK [common : include_tasks] phase.

To Reproduce

Steps to reproduce the behavior:

1. execute command `./algo'
2. Choices are sequentially: 9 y y `y` y `localhost`my public ip

Expected behavior

I expect it to build the required configuration and software

Additional context

I want to deploy it into a Ubuntu 18.04 Docker container. I have a Docker image which has built-in sudo and a sudo user. I am attaching to the container produced from this particular image, and downloading algo then following the instructions.

• I also tried running algo with sudo, got same error
• I tried troubleshooting, though it didn't seem relevant, got same error

Not sure what the error is (maybe a python version issue?), but you shouldn't use the local install option from within a Docker container.

Didn't see that, I am closing this issue for now. Thanks btw.
