Hello everyone,

I have an ASUS Chromebook. Accordingly, the operating system is ChromeOS. For a while I've been getting notifications that Upgrades for my Linux Container are available. These have never worked. Two days ago, with the help of a friend who's a programmer, I went into the Linux terminal, found the error and did the Upgrade manually (the current version I have is Debian 9, the newest is Debian 11). We used this for reference: https://www.digitentic.com/upgrading-debian-9-to-debian-11/

Now the weird thing is: It worked. The Upgrade to Debian 10 went through, no errors. Then I restarted my laptop and: I am still on Debian 9. My friend also has no idea how this happened and said he never had that happen before. So the question is: Why did the Upgrade seemingly work but it didn't actually Upgrade? And what else can we try?

I would be very grateful for any advice.

PS: for context: When I put sudo aptitude dist-upgrade into the Linux terminal now, this is what comes up:
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B of archives. After unpacking 0B will be used.

Hello and welcome.

The upgrade to 10 worked but you're still on 9? Like you and your friend, I've not seen that problem before.

The results of 'sudo aptitude dist-upgrade' in your PS indicates you're running Buster, version 10.

It's been a while since I've used Debian and cannot recall if 'sudo aptitude full-upgrade' also updates the system's version files. FWIW, what the system's version files show doesn't affect the sources.list file or what the package manager does. I also don't recall whether Debian uses an additional sources file in /etc/apt/sources.list.d. You might want to check Debian's upgrade wiki:
