The new Ubuntu 24.04 has been release but I can't upgrade the system using the update manager, because nothing appears. I have Ubuntu 23.10. I tried to change to long term releases and back to any version to no avail.
I don't know what I can do to upgrade beside installing again.
Is there a command I can use upgrade to Ubuntu 24.04 from Ubuntu 23.10 ?
From the Ubuntu 24.04 Release Notes:
"Soon after the release" typically does not mean a day or two. Historically, it has meant several weeks.
Non-LTS users are sometimes surprised by this LTS-specific delay in relase-upgrades. The much larger numbers of LTS users has led to a phased rollout of LTS releases so that the community and developers can offer the best support as inevitable problems are discovered.
do-release-upgrade -d
, which still works for a week or two until the next development release repositories are set up. However, be warned that it might fail. You may encounter unexpected behavior. Your system may become unbootable. You may lose data. The use of-d
means "I want to be a tester" and that you are willing to accept risk.Don't try to upgrade the day Ubuntu 24.04 is released
Some upgrade bugs are still getting ironed out
See this post for details: Why You Shouldn’t Upgrade to Ubuntu 24.04 LTS Yet
Just wait a week or two. Eventually when you open the Software Updater app, it will prompt you to upgrade. Big upgrades like this are rolled out in stages, so that everyone does not try to upgrade at the same time and overload and crash the download servers.
For upgrade from 22.04 to 24.04
The wait is not over yet. LTS release upgrade prompt won't appear until a few weeks after the version 24.04.1 is released in August 2024.
Hope this helps
