I can't update&upgrade anymore @ UM 18.04 v2 LTS.
Update-Manager don't open.
I do in Terminal:
/usr/bin/update-manager
Output:

A segmentation fault is normally something serious. It could be a problem with your system's installation of Python since the programs you are trying to run are written in Python.
However, all these could be failing because of a problem with Apt. Check the output of /etc/apt/source.list and clear the /etc/apt/sources.list.d/ folder (as superuser) to remove any third party sources, and refresh the cache:

I'm going to assume you are able to apt install and apt update successfully, and none of the Python applications (update-manager, software-properties-gtk, do-release-update) are able to start. It's possible Software Boutique will crash too.
Check the correct Python modules are being loaded. What is the output of this command?
The stacktrace (and code) suggests to me part of the program isn't initialising properly (likely one of the libraries/dependencies) and crashes the application as a result.
Since you say you were able to update a week ago, presumably some recent updates have broken the system? Maybe paste us a snippet of your /var/log/apt/history.log (and place in code tags please)
You probably wouldn't want to remove/purge them explicitly since that might remove many applications that depend on them.
Then try installing the software - which will automatically install the other packages it depends on:
sudo apt install update-manager
Since you're able to use Synaptic and Apt via the command line, I'm pretty sure it's a problem with your system's installation of Python. These applications are based on python3.
An error saying segmentation fault (or segfault , or SIGSEGV ) in Ubuntu and other Unix-like operating systems, or saying general protection fault in Windows, is when a program attempts to access a part of memory that cannot be accessed, or which the program is prohibited from accessing.
you need to remove /var/lib/ubuntu-release-upgrader/release-upgrade-available
and then run /usr/lib/ubuntu-release-upgrader/release-upgrade-motd
Very basically, it means your program is trying to access a memory area it is not suposed to.
2. To the current directoy.
3. You need to make sure your program doesn't do 1..
Kern.log shows me now when I try to open "update-manager+software-proper" in Terminal.
