No WiFi, ethernet, or GPU after 'sudo apt upgrade' on Ubuntu 20.04.2

us flag

I have been using 20.04.2 for a while now with no issues. I ran 'sudo apt update', 'sudo apt upgrade', and then 'sudo apt autoremove' to upgrade some packages and then rebooted.

There are some issues that are now present. My WiFi and ethernet settings do not appear in 'Settings'. I have no internet connection.

My GT 1030 GPU no longer shows in the 'About' section of settings either. It shows as 'llvmpipe (LLVM 11.0.0., 256 bits)'. However, when I go into 'Software & Updates' and view proprietary drivers, the proprietary driver for my GT 1030 shows up and is selected.

These may be separate issues or related. I'm not sure.

I did some digging for possible solutions but haven't had any luck.

I went into my '/etc/netplan/01-network-manager-all.yaml' file and this is what is present:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

It appears my netplan settings are already default. Any ideas on how to solve this?

EDIT: sudo lshw -C network

Does the OS still see the network devices? Can you [edit] your question to include the output of `lspci` and `sudo lshw -C network`? This may provide some useful information.

I was having the same problem over the last few days (After a kernel upgrade), after trying all sorts of complicated fix it turned out installing the r8168-dkms module in the Ubuntu repositories. Since apt is obviously unavailable you will need to download it on another computer and transfer via USB:

https://packages.ubuntu.com/focal/r8168-dkms

This is for the RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller in particular, there may be another available for your QCA9565 / AR9565 Wireless Network Adapter.

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.
