What does "Memory unclaimed" mean in lshw output?

Question

I just did fresh install of Ubuntu 20.04 (completely overwrote previous install). Then installed all of the firmware / software updates.

Then I ran sudo lshw -c memory, which showed

*-memory UNCLAIMED

Should I be worried about this?

Updated question... simply expecting a fresh install of ubuntu to install all necessary firmware / drivers...Don't think "UNCLAIMED RAM MEMORY is a happy state of being. — nightwatch, Dec 25 '20 at 23:11
Read your output: Looks like you installed the wrong nvidia driver package. Uninstall it. — user535733, Dec 25 '20 at 23:15
I didn't install anything.. the ubuntu installer did that... — nightwatch, Dec 25 '20 at 23:17
I removed `libfprint-2-tod1`. It doesnt allow me to remove nvidia-driver-455.. says that is not installed and none of the fix broken packages commands work — nightwatch, Dec 25 '20 at 23:26

Are the memory used by your system? Please update the question with the ourput of `free -h`. — Soren A, Dec 26 '20 at 00:57
@Pilot6 Are you saying that I should just ignore the UNLCAIMED RAM memory and the broken Nvidia-driver-455 package? straight question? LMK... I just had to do a fresh install because Ubuntu 20.04 was mystreiously freezing after an upgrade... (also showed unclaimed ram memory before fressh install). — nightwatch, Dec 26 '20 at 09:46
You can ignore the unclaimed memory, the Nvidia issue if any is unrelated. — Pilot6, Dec 26 '20 at 09:47
I also had an issue with entered data in applications not being saved properly... (ex. enter text in gnote, would disappear at random intervals) Hence that prompted to upgrade to 20.04. Then after upgrade I had this mysteriously problem no one could solve.. https://askubuntu.com/questions/1302570/ubuntu-20-04-lts-freezing-after-updating-from-18-04-updated?noredirect=1#comment2214555_1302570 So I am worried about restoring my system with the current "errors" still present — nightwatch, Dec 26 '20 at 09:51
I suggest asking another question about Nvidia. It looks like you are "fixing" your system without any reason. — Pilot6, Dec 26 '20 at 09:53
@Pilot6 just an FYI, the mysterious issues that I had under 18.04 and 20.04 seemed to related to RAM.. (20.04 clock issues, 18.04 gnote/other apps deleting / not saving info) — nightwatch, Dec 26 '20 at 11:27
So check the RAm with memtest. This is the only way to find out, — Pilot6, Dec 26 '20 at 11:28
I have done that at least 20 times, never finds a problem.. That why I finally decided o na fresh install https://askubuntu.com/questions/1302570/ubuntu-20-04-lts-freezing-after-updating-from-18-04-updated?noredirect=1#comment2214555_1302570 — nightwatch, Dec 26 '20 at 11:59

You have a new RAM controller that is not recognized properly by lshw yet.

It is not an issue at all, because all you RAM is working properly according to the free command.

I will take your advice and make a separate question about the nvidia. – nightwatch Dec 26 '20 at 10:27

the list of repositories from which it gets the packages are stored here /etc/apt/sources.list

you can use the GUI to enable all the available repos under Ubuntu Software tab, enable all the repositories including restricted and universe

then try

sudo apt-get autoclean
sudo apt-get update
sudo apt-get upgrade
