I think it looks all good. You can try to upgrade with this command,

sudo apt-get dist-upgrade

Good luck and enjoy Linux 🐧

Yes It's all working thank you very much 🧑‍💻

I found this answer to be very useful in fixing apt errors. I just used it to fix mine after installing Ubuntu on Windows only to discover that gcc was not pre-packaged with it.

Thanks for publishing the latest sources list @hakerdefo 🙏

You are trying to install an older version that is unsupported on the Ubuntu Jammy. First remove any repo file and the corresponding signing key that you might have added,

sudo rm /etc/apt/sources.list.d/ros-latest.list

sudo rm /usr/share/keyrings/ros.asc
sudo rm /usr/share/keyrings/ros.gpg

And, install ROS,

sudo apt update && sudo apt install locales
sudo locale-gen en_US en_US.UTF-8
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8
sudo apt install software-properties-common
sudo add-apt-repository universe
sudo apt update
sudo apt install curl -y
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
sudo apt upgrade
sudo apt full-upgrade
sudo apt install ros-dev-tools
sudo apt install ros-iron-desktop

Hopefully this will solve your issue.

Wow,it works!! Thanks!!

@optimuslem

Everything seems okay in your sources.list file. Could be temporary connectivity issue either at your end or at the server end.

Please help, something like this has happened. How should I fix it ?

You seem to be running ARM architecture. You should try the following in your sources.list file,

deb http://ports.ubuntu.com/ubuntu-ports jammy main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports jammy-updates main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports jammy-security main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports jammy-backports main restricted universe multiverse

Thnks a lot @hakerdefo

Hi. I'm just new in this community but I've using Linux for years and I hope I will for ever. The question is that i work like a teacher and I can't use the projector(monitor) and the TV MultimediaScreen that we have in the classrooms since I have my laptop with UbuntuStudio 22.04LTS. The TVMultimedia Screen is an APLX-65 of Promethean. In tthe webside they have as a downloads the ActivDrivers only for Ubuntu20 .04(Focal). I've been trying the two ways to install them: by the terminal and by Synaptic, but it didn't work. I'm quite desperate 'cause I need it for work, and I don't know how continue ...

Hi @hakerdefo Can help?....I live in small town where nobody uses Linux...
