I am trying to update my stretch re1 to Ubuntu 20, and I was succesfully able to update Ubuntu but when running `./stretch_new_robot_install.sh` as described in this [guide](https://docs.hello-robot.com/0.3/installation/robot_install/#run-the-robot-installation-script) I get an error during the “installation of user level pip3 packages.”  
I have attached a screenshot of the terminal for reference. I tried to attach the log error file but it said that new users cannot attach files. Any help fixing this issue would be greatly appreciated!

Hey @Edelio_Taboada, I’ve made you a “member”, so you should be able to attach files now.

Had this issue yesterday as well, I believe it had something to do with an issue running pip cache: when I attempted to run a `pip cache purge`, it would return `ERROR: unknown command "cache" - maybe you meant "check"`

First make sure you’ve upgraded pip: `sudo python3 -m pip install pip --upgrade --force`

Running `pip3 cache purge` worked for me, so I added `alias pip=pip3` to my `.bashrc` file. I suspect `pip` was trying to use Python 2 instead

Removed previous robot install from `.bashrc` and opened a new terminal, then reran the new robot install

Hope this also works for you 👍
