Wireless keyboard not working with Ubuntu 18.04 Live USB
I created a Live USB with Ubunbtu 18.04 on it so I can look into dual booting on a Windows 10 PC.
When I boot Ubuntu from USB, I can't get my wireless keyboards to work. They both work on Windows, so there is no battery issue. They both use a wireless USB dongle. The wireless mouse with one of them works fine.
I used a wired keyboard to install xserver-xorg-input-all using sudo apt-get install xserver-xorg-input-all, but the wireless keyboards still won't work
Is there anything else anyone can suggest that I try ?
Edit:
Output from lsusb is as follows -

The SanDisk device is the Live Usb and Lenovo is the keyboard/mouse. The keyboard/mouse are as supplied with the PC and are Lenovo. My alternative set with the same symptoms is by Microsoft.

Extensive history to this problem
You are not alone. Someone in Ubuntu forums has reported:
Possible workarounds
Although the bug has been confirmed by the Ubuntu Team, no one has been assigned to fixing it yet. In the meantime there are two workarounds:
Original forum post content is above, with links edited in and autocompleted where the SE system automatically resolves Ask Ubuntu question links; the bullet points were added for readability.
If you tried the Lenovo fix from WinEunuuchs2Unix's answer and it did not work, you might want to try this modified fix that I made for another Primax (HP brand) wireless keyboard + mouse combo with similar problems:

I have seen several reports of these types of problems with Primax keyboards that could not be solved with the Lenovo fix. I suspect that my modified fix might also wok for some non-HP keyboards.
