Notes, Logs, And Snaps not wokring

What are you trying to do and what exactly happens?

Which Ubuntu release do you have on your system?
Which kind of notes or logs do you want to "run"?
Which command(s) do you execute and what happens?
In case that you receive error messages, please provide the full text.

Ubuntu 18.04.5 LTS

System Logs, that comes with the system.
Just trying to run the app from the app icon.

I'm not receiving any error message.

If I try to install some snapcraft app, I'm getting an error: "Dont know how to handle snap://...*" inside the Software app

For diagnostic purposes please provide the output that you receive for the following commands (to be executed in a terminal):

uname -a
lsb_release -crid
apt-cache policy snapd
sudo dpkg --audit

sudo dpkg --audit:

Empty result.

If you are searching logs I'd recommend using grep in the terminal. It's super powerful

"Dont know how to handle snap://...*"

Try the following:

sudo apt install --reinstall snapd
snap --version

and copy/paste the results.

Reinstall snapd gives the following print:

There seems to be a problem with the repository server that you have selected.

I suggest that you switch to a different repository server in your vicinity (e.g. by using the program software-properties-gtk) and then run the commands

sudo apt update
sudo apt full-upgrade
sudo apt install --reinstall snapd
snap --version

and copy/paste all output that we can check.

Ok. did it again, and changed the repo.

now after I run the reinstall of snapd I get this:

sudo apt install --reinstall snapd

still need support on that

Okay. YES. It did help.

BUT now:

Trying running notes works well and good as it should now. But trying to run Logs app, is successful but the app has no background, only white text.

Which "Logs app" are you taking about?

ok.. now after some time the system worked, The logs app works fine.

So its all good. Thank you!

Thanks Manfred Hampl, that solved my question.
