Discover updating error

leinad47 · 2025-10-22 20:53

Hello! I am struggling with this error every time I open Discover.
E: Type 'sudo' is unknown in line 3 of source list /etc/apt/sources.list
E: Source list cannot be read.
How can I fix it?
Thank you all!

By the sound of it there is something wrong in one or more lines of your sources files.
Please open Konsole/Terminal and type

inxi -r

Copy and paste the results back here.

leinad47 · 2025-10-23 11:02

Thank you for your help. As soon as I get home in the evening I will follow your suggestion I will paste the results back here.

@leinad47
Well, now run commands:
$ cat /etc/apt/sources.list
$ ls -al /etc/apt/sources.list.d/
and post the output here.

Yes, you have malformed /etc/apt/sources.list file. Do you know what did edit this file ?

The file should be empty, so make it empty and run again:
.$ sudo apt update

leinad47 · 2025-10-23 16:04

Thank you. Since I am quite new to Linux I may ask you dumb questions. Please suffer with me. For instance, where should I go to make the file empty?

Edit the file /etc/apt/sources.list as root, delete all the text and save it.

leinad47 · 2025-10-23 16:13

Where is this file I need to edit? I tried to find it in Dolphin and in the search menu, but I could not find it. I typed in the Konsole the fie name, b I got this: ”the source cannot be read”. Sorry for troubling you.

q4osteam · 2025-10-23 16:21

You are welcome
- Run Dolphin
- Navigate to /etc/apt folder
- Right click on the "sources.list" file
- Edit as admin

You had to do some non standard action as the file is broken. It would be better to figure out what happened to avoid repeating such a situation.

This message shows some issue with clock skew. Try to reboot and run the command once again.

leinad47 · 2025-10-23 16:38

I rebooted the computer, but unfortunately I got the same error notice when trying to do the updates in Discover. How to fix this issue with clock skew?

leinad47 · 2025-10-23 16:40

I also ran again $ sudo apt update, but I got the same result.

Configure your timezone properly
$ sudo dpkg-reconfigure tzdata
Run:
$ date
and post back the output.

Time looks like it is OK

This is not ok, UTC time should be "15:52:47 UTC" instead of "03:52:47 UTC".
Run:
$ timedatectl
