After receiving the respective notification on May 15 2024, I tried to update Jupyter Lab version 4.0.11 to version 4.2 on my Linux desktop.

I entered:

conda update jupyterlab 

In the terminal. It seemed to proceed normally. Next I entered:

jupyter lab --version

and got the answer: 4.0.11. I then tried to update a second time. This time it told me that:
** All requested packages already installed.** But it still showed version 4.0.11.

How can I update to 4.2?
