i lunched this command in ubuntu 18.04 terminal: pip install -U rasa-x --extra-index-url https://pypi.rasa.com/simple
and i’m still stuck in this step for long time:
Using cached h11-0.9.0-py2.py3-none-any.whl (53 kB)

thanks its working but i have another issue
The path ‘config.yml’ does not exist. Please make sure to use the default location (‘config.yml’) or specify it with ‘–config’.
that error shows me : alembic.util.exc.CommandError: Can’t locate revision identified by ‘d741ab0a01aa’
Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up.

sudo -i
```
To start a root shell, then make a backup of root's `.Xauthority` if needed
```
test -f .Xauthority && mv .Xauthority .Xauthority.bak
```
Copy the file from your home to root's
```
cp -a /home/youruser/.Xauthority .Xauthority
chown root: .Xauthority
```
Then you can start Firefox with:
```
XAUTHORITY=/root/.Xauthority sudo firefox
```
Remember to `exit` the root shell when you've finished with it.
Also remember to unroll your `.Xauthority` backup when done:
```
sudo -i
test -f .Xauthority.bak && mv .Xauthority.bak .Xauthority
exit
```
OR
sudo chown -R $USER:$USER ~/.mozilla
