sudo do-release-upgrade -cd
返回
Checking for a new Ubuntu release
New release '22.04' available.
Run 'do-release-upgrade' to upgrade to it.
然后
sudo do-release-upgrade
返回
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.
我认为错误是:
22.04 未标记为 LTS。因此do-release-upgrade
不适用于从 20.04 LTS 升级到 22.04 LTS。
任何解决方法除了set Prompt=normal in /etc/update-manager/release-upgrades.
