General Updates

Update One-liner

To Update without further confirmation:

sudo apt update -y && sudo apt upgrade -y

sudo apt update -y && sudo apt upgrade -y

Remove the -y flag to manually confirm actions

Fix Update Problems

Removes bad cached packages and re-download

sudo rm -f /var/cache/apt/archives/linux-headers-6.8.0-94_*.deb
sudo apt clean
sudo apt update
sudo apt --fix-broken install

sudo rm -f /var/cache/apt/archives/linux-headers-6.8.0-94_*.deb
sudo apt clean
sudo apt update
sudo apt --fix-broken install

If this has run successfully you can trigger updates, I had best success with removing obsolete packages beforehand

ubuntu: podman & podman compose

Choose the right container Setup

In the past i used docker a lot. Since they moved on more to please enterprises I prefer to use podman and podman compose.

Install Commands for podman & podman compose

sudo apt update
sudo apt install -y podman podman-compose
podman --version
podman compose version || podman-compose --version
systemctl --user enable --now podman.socket

sudo apt update
sudo apt install -y podman podman-compose
podman --version
podman compose version || podman-compose --version
systemctl --user enable --now podman.socket

Optional: make sure your user has a subuid/subgid range (needed for rootless features)
