I’ve been diving into Ubuntu lately, and I came across this whole process with the release upgrade command, but honestly, I’m still a bit hazy on the details. I mean, it feels like there’s a lot that goes into it, and I’d love to hear how it actually works.
So, when you run a release upgrade command in Ubuntu, I get that it’s supposed to help you jump from one version to the next, but how exactly does it know what version you’re on and what the next one is? Is there a checklist it goes through to ensure everything is compatible before doing the upgrade?
I’ve seen people mention using commands like `sudo do-release-upgrade`, but what’s happening behind the scenes? What are the steps it takes once you hit enter? Are there specific dependencies or configurations it checks for? And what does it mean when it says it’s downloading the necessary packages and upgrades? Is it pulling those from the main repositories, or does it check for some sort of mirror?
Also, I’ve experienced those moments where you’re trying to upgrade, and you hit a wall because of broken packages or unsupported PPAs. How does the command handle those situations? Does it give you a way to fix things on your end, or is it more like ‘sorry, try again later’?
And let’s talk about the aftermath—what happens post-upgrade? It sounds like some people have experienced issues with their configurations or programs not behaving as they should. What do you usually do in those cases? I’m keen to learn if there’s a way to back things up beforehand to avoid mishaps.
Honestly, I just want to make sure I’m not fumbling in the dark on this because upgrading can feel a bit daunting at times. It would be awesome to hear some real-world experiences from those who have gone through the process or have tips on making it smoother!

When you run the command
sudo do-release-upgradein Ubuntu, the system initiates a comprehensive process to facilitate the upgrade to the next release. It starts by checking your current version against the latest available versions in the configured sources, usually the main Ubuntu repositories, and it identifies which version you are on and what the next one is. The upgrade tool will perform various checks to ensure compatibility, such as inspecting the installed software packages, their dependencies, and configuration files. If there are any unsupported third-party Personal Package Archives (PPAs) or broken packages that could potentially cause issues during the upgrade, the tool will flag them, allowing you to address these problems beforehand. It also downloads the required packages from the repositories or mirrors configured on your system, ensuring that the newest versions of software are installed.Once the upgrade process begins, it takes several steps which include downloading packages, updating your system’s package database, and configuring the newly installed software. If you’re faced with issues like broken packages, the upgrade tool provides feedback on what went wrong and may suggest commands to fix them, such as using
apt-getto resolve dependencies or remove conflicting packages. After the upgrade, it’s advisable to reboot and verify system functionality, as some users might encounter configuration issues or services that no longer operate correctly. To mitigate these risks, it’s crucial to back up important data and system configurations beforehand using tools likersyncortar. By following these practices and understanding the underlying processes, you can navigate the upgrade path more smoothly and reduce the likelihood of encountering significant problems.“`

Once you invoke the command, it follows several steps:
What About Broken Packages?
If you encounter broken packages or unsupported PPAs, the command typically provides some guidance but may not fix everything for you. It might suggest running commands like
