Unable to Successfully Install Mojo via 'modular install mojo' on Ubuntu 20.04

[Live-yan]

I am encountering difficulties while attempting to install Mojo on two Ubuntu 20.04 systems using the 'modular install mojo' command. One server is located in the United States, while the other is in Shanghai, China. Despite multiple attempts on both machines, I have consistently obtained the same output, with the installation process stalling at the following point:

root@racknerd:~# modular clean

Both of my machines halt at this stage, and I have even waited for 6 hours, but still no result.

I would greatly appreciate any assistance or insights from the community regarding this issue. Here are some additional details that might be helpful:

Operating System: Ubuntu 20.04
Command Used: modular install mojo
modular --version: modular 0.1.4 (6b54d308)

I have followed the installation steps as outlined in the Mojo documentation, but I seem to be unable to proceed beyond the aforementioned point. I have also verified that all necessary dependencies are installed on both systems.

If anyone has encountered a similar problem or has any suggestions on how to resolve this issue, please share your insights. Your assistance would be highly appreciated!

Thank you in advance for your help.

If you are on a windows system, WSL2 is a must.

I am using an Ubuntu 20.04 virtual machine, not WSL

Hello, it seems you are using python3.8, (mojo does support from 3.10 to 3.8 : https://docs.modular.com/mojo/manual/get-started/)
nbformat>=5.1.2 in /usr/local/lib/python3.8
Maybe you can try with python 3.11 and 3.0, i really don't know but if this can help?
Also i see you are installing as root, you could try to install install inside a .venv as a normal user if you think it would help?

I had to give up multiple attempts to install Mojo in a virtual machine due to the poor network environment. However, I have successfully installed and been using Mojo in GitHub Codespaces.

Ok, i am not familiar with virtual machines, however, mojo does run on Ubuntu 20.04 !
