I'm using Ubuntu 18.04.3, this one I installed last November and never have any problem so far.
Just around an hour ago after I restart my PC to clear some GPU memory, I found Google Chrome missing, I install that from .deb file and then then found out that the LAN menu went missing as well and I have to use wifi shered from phone now.
I didn't even run a single sudo in that session, just run some Python and Dota in steam. The only thing that not normal is that Tensorflow raise core dumped more often but I fixed it according to this, so I don't think this is related.
Later I found out that Redshift and VSCode are missing as well, from both terminal and launcher, don't know if there's anything else though. Checked it later and found out that VLC is gone too and got unmet dependencies so I can't re-install it.
The software's' setting are all safe and sound.
What's went wrong here exactly and also, how to bring the LAN back? Also some other softwares that suddenly have unmet dependencies.
My LAN works fine when I switch to Windows 10 though.
Software&Update somehow looks like this. I can only thick the Continue... but cannot Apply Changes, cannot thick anything else either.
I got this when run sudo lshw -c network

The word DISABLED is gone once I run sudo ip link set dev enp0s31f6 up but nothing else happens. The network menu still not show up and it goes back to DISABLED after I restart.
This doesn't work neither does this nor this.
Got this after run sudo smartctl --all /dev/nvme0n1
