Sorry, it's my primary work environment so I can't do a fresh install. Please let me know if any info I can provide for you to debug.

@smuniraj2018 I have tried to fresh installed it and this time it works fine.

I didn't document my installation steps for the first installation where it crashes, but here's what I did for the second installation:

#!/bin/bash

password="assume password here"
auth="assume auth here"

# install python
echo "$password" | sudo -S apt update
echo "$password" | sudo -S apt install python3.10
echo "$password" | sudo -S apt install python3.10-venv

# install modular
curl https://get.modular.com | \
  MODULAR_AUTH=$auth \
  sh -
echo "$password" | sudo -S apt update
echo "$password" | sudo -S apt install modular

# install mojo
modular install mojo
echo 'export MODULAR_HOME="$HOME/.modular"' >> ~/.bashrc
echo 'export PATH="$MODULAR_HOME/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

# test your installation
# create a new hello world file
mkdir Mojo
cd Mojo
echo "fn main():
    print(\"Hello, World!\")" > hello.mojo

# run the file
mojo run hello.mojo

# and it worked

I didn't really "run" this script because this script I wrote would somehow skip the python-env installation (I'm not experienced enough to understand why), so I ran it manually, one or a few command at each time.

[sangshuduo]

inspired by #1087 (comment) I removed ~/.modular directory and installed python3.10-venv, then used "modular auth XXXX && modular install mojo" now mojo 0.4.0 is installed.
