I am getting unable to locate errors when trying to apt install rosserial (noetic)

sudo apt-get install ros-noetic-rosserial

just like

which is resolved but doesn't seem to be working for me. I have updated my apt cash but no change. I'm about to just install from source but is there something small I'm missing?

I do not have any issues installing on Ubuntu 20.04 with the same command

sudo apt-get install ros-noetic-rosserial

As suggested in the GitHub thread, try running sudo apt update first.

Thanks for confirming yours works but I really don't know what to tell ya...

Same thing on two different machines

To be sure, have you also run steps 1.2 and 1.3 in the install guide before running sudo apt update?

@masynthetic when you ran sudo apt updateI see you have the ROS2 PPA from your imgur picture. When I run the same command it gives me ' focal InRelease' not what you have which is ' focal InRelease'. Maybe that is the problem?

@jacobperron@JackB thanks a ton you were both correct that this was my issue. I am very new to ROS and I don't believe the tutorial I followed to install ROS has this step or at least I missed it.

I just followed 1.2 and 1.3 exactly, updated apt and tried again and it worked. Did not re-install ROS or anything, do you think that I should reinstall with the updated source list?
