Software & Updates is not working?

[rabillo]

First I got a error message when I typed sudo apt update in the terminal.

"E:Conflicting values set for option Trusted regarding source Index of /drivers/ jammy, E:The list of sources could not be read."

Here with a red warning button.

After that, I can't use Software & Updates, Software Updater. Can you help me?

[nfratom]

run sudo apt update and then post the output here

[rabillo]

E: Conflicting values set for option Trusted regarding source Index of /drivers/ jammy
E: The list of sources could not be read.

this is the output.

[rabillo]

This is the notification.

Could You open the Terminal and run sudo apt update && sudo apt upgrade there. Because in the Terminal You should get further Output than with this Message. And when You have that, post please all of it here.

Another Thing: Do You have choose ''Main Server'' as Source in the Settings of Software & Updates?

[rabillo]

Here,
Also I directly can't access to Software & Updates it is not opening when I click.

@rabillo

Also I directly can't access to Software & Updates it is not opening when I click.

For this You have a couple of Options to get in.

1. Open the Software Updater and click on the Stopp Button. Then click on Settings.

2. Open the Gnome Software Center. Click there on the Settings Button beneath the min/max/close Button and choose the Option ''Software Sources'':
   
   Please don't be irritated by the Language. My System is in german.

3. When You go in the App Grid, you should find a Symbol for Software & Updates.

I also can't open the Software Updater
2 apps is not opening + sudo apt update is not working

[Ponce-De-Leon]

And the other Options are not working, too?

[rabillo]

Yes, when I click the "Software Repositories" is not opening too.

[Ponce-De-Leon]

Hmm ... for me it looks like that something is broken. What did You before this Problem appears? Did You install Software, made an Update or something?

[rabillo]

Thanks, I was looking for the nvidia driver settings in the app maybe that was the problem. I just boot the ZorinOS again.

[Ponce-De-Leon]

So, You looked on the ''Additional Drivers'' Tab? And then? Did You made anything there?

[rabillo]

Yes, I think I change the settings. Like nvidia-driver-535 to nvidia-driver-545. After that I booted the ZorinOS in advanced options. Now I am using in the old boot selection.

[Ponce-De-Leon]

The 545 Driver could be the Issue if You should use the 6.8 Kernel. Both are not running good together:

After update, display is really slow and screen is tearing

Thanks for the flag @zabadabadoo! We've investigated this issue and have found that specifically the upstream proprietary NVIDIA 545 driver package currently doesn't have a kernel module that's compatible with Linux 6.8 yet. We've found that most other versions of the NVIDIA driver package should nevertheless be compatible with the latest kernel update: 550 545 535 530 (auto-upgrades to version 535) 525 (auto-u…

So, did you removed the 545 Driver?

[rabillo]

I didn't remove just change the select option but after that I can't boot. I can use safety mode and the older version select in the advanced options for boot screen.

[Ponce-De-Leon]

Then it would be good to remove the Driver. So, open the Terminal and type sudo apt remove nvidia* libnvidia*

That will delete the Nvidia Drivers. After that install the Nvidia Driver again with sudo apt install nvidia-driver-535 for the 535 Driver or type sudo apt install nvidia-driver-550 for the newer 550 Driver.

[rabillo]

Thanks! I use the safety mode, remove and install the drivers in root. That worked.
