Unable to locate package

I had this once before but forgot how I fixed it. New install 2020.2. I can get on-line, and I am logged into this site with the OS. But no update work.
Tried to update airgeddon but I get the "Unable to locate package". Thanks to anyone that can help.

What are the commands you used?
This should work:

Code:

---

sudo apt update
sudo apt install <package name>

---

to install or update an existing package.

Code:

---

sudo apt update
sudo apt upgrade

---

Code:

---

sudo apt update
sudo apt full-upgrade

---

to upgrade all packages currently installed on the system.

Type

Code:

---

man apt

---

To get more details.

Are you sure that "airgeddon" is a Kali package?
You can use

Code:

---

apt policy airgeddon

---

and

Code:

---

apt search airgeddon

---

to check.

Hope that helps.

Thanks so much! I'll give it a try.
