升级方法:
我这里只针对已有ubuntu的用户
打开ubuntu 或 Windows Terminal,运行命令do-release-upgrade。
frank@LAPTOP-0OCJTGJR:~$ do-release-upgrade Checking for a new Ubuntu release There is no development version of an LTS available. To upgrade to the latest non-LTS develoment release set Prompt=normal in /etc/update-manager/release-upgrades.
可能会出现上面的报错信息。
打开文件sudo vi /etc/update-manager/release-upgrades
# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for, or allow upgrading to, a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the supported release that immediately succeeds the # currently-running release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that if this option is used and # the currently-running release is not itself an LTS release the # upgrader will assume prompt was meant to be normal. #Prompt=lts Prompt=normal
默认设置时Prompt=lts,将其改为Prompt=normal.,重新执行命令do-release-upgrade
期间会有两次人工参与
