我一直在尝试升级到Ubuntu 18.04,但是,当我尝试


do-release-upgrade -c



我得到这个输出


Checking for a new Ubuntu release


No new release found.




答案1

Release Notes


答案2

在这里提供了完整的升级指南,


do-release-upgrade -d # Use this until 18.04.1 comes out


do-release-upgrade # Use this after 18.04.1 comes out



另外,尽管你需要检查文件:


~$ cat /etc/update-manager/release-upgrades


# Default behavior for the release upgrader.



[DEFAULT]


# Default prompting behavior, valid options:


#


# never - Never check for 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 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 this option should not be


# used if the currently-running release is not itself an LTS


# release, since in that case the upgrader won't be able to


# determine if a newer release is available.


Prompt=never



如果最后一行显示"never",对于Ubuntu 17.10用户,请将其更改为"normal"。对于Ubuntu 16.04 LTS用户,请将其更改为"LTS"。否则,您不会获得升级.
