Ubuntu 18.04 freeze after each reboot

Hello all,

I´m running Ubuntu 18.04. Since last week I´ve been struggling with rapid freezing - it appears after approximatelly 5 minutes. The only way is to reboot the system. I haven´t performed any update.

The details of Ubuntu. No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.3 LTS Release: 18.04 Codename: bionic

When typing "uname -r" the result is: 4.4.0-18362-Microsof. linux-generic-hwe-18.04 is already the newest version (5.3.0.42.99). xserver-xorg-hwe-18.04 is already the newest version (1:7.7+19ubuntu8~18.04.3).

I´ve tried many corrections I googled but still without any success. I´m new to Ubuntu. Please, could you help me? Where is the problem?

Thanks a lot
Regards
Adam

I have no answer, just more questions. You need to provide additional information if you expect help.

4.4.0-18362-Microsof. linux-generic-hwe-18.04

Is that really the kernel version string? Doesn't look right.
Then you say

already the newest version (5.3.0.42.99)

So, is it 4.4.0 or 5.3.0?

What do you mean by "freeze"? Can you access the frozen computer from the network, ping or ssh? Can you open a virtual terminal on the console (ALT-F1, ALT-F2 etc)? Or is it totally unresponsive?

Does it freeze only if you use the GUI or also when you boot into non-graphical mode?

Have you ever used this computer without freezing? If so, was it with the same Ubuntu installation or some other OS?

Has this started suddenly, can you connect the start of the freezes with any event or action?

Ubuntu should have inxi. My command below will show your computer specs.

inxi -v8 -z

Sometimes hardware freeze's in my experience is failing hard drive.
Mem test might be called for also.

Google will tell yu what I mean.

Let me better clarify my situation. I´m running Windows 10 64 bit (Intel r Core tm i5-5300 cpu) and using Ubuntu 18.04 for accessing some Linux-based programs thus I´m really new to Linux. I was using Ubuntu 18.04 for several last months without any problem but since last week Ubuntu freezes after approximately 5 minutes using. The only possibility is to reboot (shutdown) the whole system and Ubuntu then is working (just for other 5 minutes). If I mean freeze, any code in Ubuntu abruptly stops running and can´t do anything - I can type whatever I want but there is no response. It´s no problem to quit Ubuntu. Other Windows programs run without any problem. There hasn´t been any update that would cause this issue.

When typing "uname -a" ( all information regarding the kernel version): Linux DESKTOP-BKA8EK5 4.4.0-18362-Microsoft #476-Microsoft Fri Nov 01 16:53:00 PST 2019 x86_64 x86_64 x86_64 GNU/Linux. So the exact Kernel Version should be 4.4.0-18362.

So the problem is related to the Ubuntu only I guess. But as I said sinceI don´t work with Linux at all and with Ubuntu just occasionally I don´t know how to address this issue. Please, could you advise me?

I assume you are dual booting. Might be easier to run a virtual machine to double check or even just use instead of dual boot. I'd also be sure to test the disc or iso you used.

I'll also have to ask if you installed linux from windows store?

I doubt uname/kernel version has any great benefit.

We can't say it is related to linux just yet.

Can you boot to some other distro (that has been tested)

If you can't type anything, how do you quit or reboot Ubuntu?

Other Windows programs run without any problem. ... When typing "uname -a" ( all information regarding the kernel version): Linux DESKTOP-BKA8EK5 4.4.0-18362-Microsoft #476-Microsoft Fri Nov 01 16:53:00 PST 2019 x86_64 x86_64 x86_64 GNU/Linux.

Could it be you are running Ubuntu on WSL (Windows Subsystem for Linux)? If so, I have no suggestions for you, as I am quite unfamiliar with all the potential problems of this framework.

I´ve found out the problem is related to WSL since they released the update of the WSL Linux kernel (https://docs.microsoft.com/en-us/win...sl/wsl2-kernel). After this update (I didn´t know about it) the freezing problems occur. Please, if you had any advice how to address this issue I would be very grateful for it.
