Error installing Docker Desktop on Linux Mint

Task:

On 2/9/2023, try to install Linux version of Docker Desktop 4.16.2 on Linux Mint Una 20.3, following these steps.

Obstacle:

Repository update command fails:

~$ sudo apt-get update …                                                         Err:13 https://download.docker.com/linux/ubuntu una Release                                              404  Not Found [IP: 2600:9000:234b:f400:3:db06:4200:93a1 443] Get:14 http://security.ubuntu.com/ubuntu focal-security InRelease [114 kB] Reading package lists... Done                                                                                            E: The repository 'https://download.docker.com/linux/ubuntu una Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

Package install command fails:

~$ sudo apt-get install ./Downloads/docker-desktop-4.16.2-amd64.deb Note, selecting 'docker-desktop' instead of './Downloads/docker-desktop-4.16.2-amd64.deb' Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: docker-desktop : Depends: docker-ce-cli but it is not installable E: Unable to correct problems, you have held broken packages.

Diagnosis:

The installation steps create a repository sources file /etc/apt/sources.list.d/docker.list that looks like this:

deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu una stable

"una" is the Linux Mint release name, but the Docker repository uses Ubuntu release names. The corresponding Ubuntu name should be "focal."

Resolution:

I changed the release name in the docker.list file from una to focal:

deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu focal stable

After editing docker.list, I ran the apt update & install commands & completed the install of Docker Desktop.

Yacht vs. Portainer - Docker dashboard comparison - Virtualization Howto

Docker Dashboard is a web-based GUI for managing Docker containers, images, networks, and volumes. It provides a centralized view of the containers running on a host, the resources they are consuming, and their performance metrics. The dashboard also provides a way to access and manage Docker components, including images, networks, and volumes. The main benefit of using the Docker Dashboard is that it simplifies the process of managing and monitoring your Docker environment, making it easier to understand your system’s resource utilization and performance. There are many options for this purpose. This article compares two famous of them (Yacht and Portainer).

If you are interested in pursuing a career as a DevOps Engineer, you should probably go to Berlin. Every single time I'm searching for a job in Berlin, another tech company is looking for a DevOps Engineer, I still have no idea what it is and my brain can't comprehend the Silicon Valley Google search results.

90% of the English-speaking job market in Berlin is just computer science hell, extremely important corporate jobs, or customer service call centers. Every time I apply for jobs within my skillset (I.E. Motion Design) I keep getting rejected.

This is super exhausting.
