# Upgrade Jupyter 4.4 to latest

Thank you Leon, but my problem was not knowing that jupyter and jupyter-notebook are two separate programs.
I installed a .deb package from the following site and it solved my problem with fastai notebooks.
[https://debian.pkgs.org/10/debian-main-amd64/jupyter-notebook_5.7.4-1_all.deb.html](https://debian.pkgs.org/10/debian-main-amd64/jupyter-notebook_5.7.4-1_all.deb.html)

Hello,
My tensorbook came with Jupyter 4.4 preinstalled. How do I upgrade it to the latest version?
sudo apt-get upgrade is not working.
I am planning to run some fast.ai V3 notebooks, but the older versions has some problem that is preventing me from running any of these notebooks.
Please let me...

# Keyboard Protector Cover

Hello forum,
I just got my lambda tensorbook today.
I would like to know if anybody here got a keyboard protector cover for their laptop.
Something similar to this.

I would like to know the exact cover you got that would fit this notebook’s keyboard.
Thanks,
Chandana
