I'm having the same problem.

The problem is:

dpkg: error processing archive ./xserver-xorg-input-evdev_1%3a2.10.6-1+b1_armhf.deb (--install):
 package architecture (armhf) does not match system (arm64)

You see the driver is for armhf not arm64.

Okay, but is there any solution to this?

Yes the solution is to reflash the sdcard with the armhf version of the os.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
