When I ran sudo apt upgrade the last time, there appeared the following warnings:

Unless you have one of those Intel CPU/GPU then not a problem. "W" means warning, not an error.

Please run: `sudo lshw | grep i915` Is that driver in use on your system? If not, ignore the warning.

@chili555 the output was configuration: driver=i915 latency=0. Does this mean the driver in use and I need to take care of the warning?

The needed files are present in the focal-updates, appropriate for Ubuntu 20.04, version of linux-firmware.

Please do:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.187.20_all.deb
sudo dpkg -i linux*.deb

Reboot and check the message log:

sudo dmesg | grep i915

Is the warning resolved?

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.
