To exit from the container use CTRL-C. You can remove the container by using the container id. Get the id and stop the container using these commands:

podman ps -a podman stop <container_id>

You can delete the images from your machine by using the following command:

podman rmi <image_id>

An easier way to create a shortcut is to symlink the desired command name to the flatpak export. Create the symlink in a folder already in your PATH to avoid getting tab completions with a bunch of org and com commands.

ln -s /var/lib/flatpak/exports/bin/com.visualstudio.com $HOME/.local/bin/code

The symlink can always exist, but if the target file does not exist your shell should be smart enough to not execute or tab complete it.

While a device is correctly detected at /dev/ttyUSB0 and owned by the dialout group, adding myself to that group doesn’t work as it can’t be found. This is because under Silverblue, there are two different group files (/usr/lib/group and /etc/group) with different content.

There are some easy ways to solve this, for example we can create the matching dialout group or write a udev rule.

If you try to add yourself to the dialout group it will fail. sudo gpasswd -a ${USER} dialout gpasswd: group 'dialout' does not exist in /etc/group

Trying to re-create the group will also fail as it’s already in use. sudo groupadd dialout -r -g 18 groupadd: GID '18' already exists

So instead, we can simply grab the entry from the OS group file and add it to /etc/group ourselves:

1 grep ^dialout: /usr/lib/group |sudo tee -a /etc/group

Now we are able to add ourselves to the dialout group:

2 sudo gpasswd -a ${USER} dialout

Activate that group in our current shell:

3 newgrp dialout

And now we can talk to the arduino.
