So I found out that my installation of Ubuntu doesn't have nm-connection-editor. I tried installing it but it said package not found. After a bit of searching I came across that I will have to install network-manager-gnome for that. I tried installing it and I got this issue:
$ sudo apt install network-manager-gnome
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
network-manager-gnome : Depends: libnma0 (= 1.8.24-1ubuntu2) but 1.8.24-1ubuntu3 is to be installed
Recommends: mobile-broadband-provider-info but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried using sudo apt install -f network-manager-gnome but it did not work. I would appreciate some help regarding this.
network-manager-gnome(https://packages.ubuntu.com/focal-updates/network-manager-gnome) on an updated 20.04 system does not have a depends rule for the version you specify, but instead "libnma0 (= 1.8.24-1ubuntu3)" so you're likely not using Ubuntu 20.04 or are sourcing that package from a non-Ubuntu source, thus its a source issue. Start withsudo apt update& read the output, any warnings, missing lines, errors etc? It'd be helpful to if you were specific; Ubuntu 20.04 Desktop? Ubuntu 20.04 Server? etc – guiverc Apr 27 '23 at 06:30
