Ubuntu 24.04 Wired Connection App Center No Internet?

Support and Help
1

I am able to browse the internet with no problem. When I search for a package in the App Center it searches, appears to time out, and then throws up a message stating there is no internet connection.

This is the same wired connection that I used to install Ubuntu 24.04 without issue and am able to search the internet using Firefox. I was also able to update the installed packages to current using the update function. Is there something unique about the App Center and how it accesses the internet or is this an erroneous error? I am attempting to find the mythtv packages.

The App Centre has no special requirements for accessing the internet

Nevertheless, there are other ways of finding the info
Try these terminal commands:-

apt-cache search <package name>

For example
apt-cache search mythtv

apt show <package name>

apt policy <package name>

Finally, as an alternative to the App Centre, synaptic is a popular choice to search/install software
sudo apt install synaptic

Do have any proxy settings or DNS settings that might have changed?

The app center comes as a snap, to check if your snap packages can generally reach the internet at all you can run:

snap debug connectivity

(though if your browser (which comes as snap package as well by default) can reach the internet this part should be fine)

Are you using any kind of proxy in your network setup ? you can explicitly tell snap packages to use a proxy via:

sudo snap set system proxy.https="..."
sudo snap set system proxy.http="..."

Thank you for your quick response. Working on this today, I believe my problem is that I have my router country filtering tightened down too far. This is really a networking rules issue rather than an Ubuntu issue. This item is closed.
