Can upgrading Ubuntu cause the 'libncurses.so.5' error, and how can it be resolved?

Yes, upgrading Ubuntu can sometimes lead to this error because the library may be removed or moved during the upgrade. Reinstalling libncurses5 using `sudo apt install --reinstall libncurses5` is a good first step. If this doesn't work, you may need to check the package's dependencies and ensure they are also correctly installed or reinstalled.
