Missing settings pannel + missing internet control (Ubuntu 20)

us flag

I am facing a very annoying problem. This week, I saw two things waking up on my Ubuntu when I woke up.

  1. I no longer have "settings" graphical interfaces ...
  2. I no longer have internet.

One with the other, it's quite crippling. I am on Ubuntu 20.04 LTS Focal Fossa kernel 5.4.0-86-generic.

My PC : Asus ROG Strix Scar II with Nvidia. I am dual-booting with Windows 10. I am the only user. I specify that I really cannot access the settings, I no longer have the tab.

I looked for and carried out some commands which have not given anything yet, I will communicate the results to you anyway.

sudo lshw -C network

The files in NetworkManager and netplan look fine, based on all the problems I have read.

My Problem : I want to find my settings panel. I want to be able to connect to the internet again.

I must say that I am very close to reinstalling Ubuntu ... But I leave a chance before for the expertise of the community. What an obscure problem .. Thank you !

OK, I solved my problem. I explain if anyone encounters the same concerns.

Unfortunately I can't wait, I need Ubuntu to be available very soon. I found a very interesting post that I recommend following if you are in the same situation : this

Although nothing worked for me, I followed the reinstall procedure for Ubuntu 20.04. Chapter "Method 1 : Reinstall without touch "/home"".

By following this exactly, I was able to find Ubuntu exactly as it was, with my folders, files and configurations.

Only need to install packages disappeared with apt-get. They will revert to the configuration you left before the reinstallation.

So I once again have access to the settings application and to the connection settings and I found the internet.

Thank you very much for your answers @guiverc

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
