Ubuntu Update Manager

Hello,

The error message is incomplete, so it's hard to respond.

Several possible explanations:

• the internet connection is not working
• one of the repositories configured in /etc/apt/sources.list or in a file contained in /etc/apt/sources.list.d is invalid
• one of the repositories configured in /etc/apt/sources.list or in a file contained in /etc/apt/sources.list.d is currently down.

To get a clearer picture, could you type the following command in a terminal and copy-paste the result?

sudo apt update

(You will need to type your password blindly and then press enter).

Good luck

Re:

Comment on line 2 of:

/etc/apt/sources.list.d/third-party.sources

By adding # in front

Example:

#URI

Just add # with a text editor like nano or others, save and start again

Sudo apt update

Hello,

Please avoid screenshots as they are not practical for anyone; it's better to copy and paste (see this tutorial).

The error message (see message #2) means that there is an error on the first line of the file /etc/apt/sources.list.d/third-party.sources. Therefore, you need to correct this file with a text editor launched with root privileges and fix the problematic line (the first line containing a URL) or comment it out (by adding a # at the beginning of the line). To edit this file:

sudo gedit /etc/apt/sources.list.d/third-party.sources &

To correct the offending line, you should copy and paste the content of this file so we can guide you on how to fix it, so in the meantime, the best approach is probably to comment it out.

Once done, save and exit. Then run:

sudo apt update

Furthermore, it seems very strange that you do not have a file /etc/apt/sources.list because this means that your Linux is no longer tracking standard updates. You should create this file and fill it out according to the documentation. You can find it in the Ubuntu documentation.

sudo gedit /etc/apt/sources.list &

Its content should be:

 deb http://fr.archive.ubuntu.com/ubuntu/ noble main restricted deb http://security.ubuntu.com/ubuntu noble-security main restricted deb http://fr.archive.ubuntu.com/ubuntu/ noble-updates main restricted

Finally, I see that in /etc/apt/sources.list.d you are mixing repositories related to different versions of Ubuntu (focal, jammy) while your main system seems to be on another version (noble). This is generally a bad idea, unless you have no choice (which I doubt), it's better for all your sources to align on the same version of Ubuntu, the most recent one (in this case, noble).

Good luck

Good evening

I just installed Ubuntu 22.04.3 LTS

No problems

Thank you all
