Answer 1

If I'm not mistaken, you've installed a 32 bit version of ubuntu. Then you need a 32 bit deb file - and you tried to install the 64 bit. First you need to remove the "wrong" deb version.

Then update.

sudo apt update

Select and install the 32 bit deb version from Anydesk and you should be fine

Ubuntu will cease to support 32 bit. So it is a good idea to install a 64bit operating system on your Lenovo G500s (which has a 64 bit Windows by default)
