我有一个 Wily 盒子,它没有升级到 xenial,它不会抛出错误或抱怨依赖关系,它只是说没有什么可更新的。这是 ubuntu Mate。
$ sudo apt-get update
...
$ sudo update-manager -d
$ sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found
$ sudo lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily
我应该手动更改源列表吗/etc/apt/sources.list
?
答案1
尝试更改目录release-upgrades
中的文件/etc/update-manager
,在该文件中您可以使用选项升级到 LTS 或正常版本升级:
sudo nano /etc/update-manager/release-upgrades
将 prompt 的值从 更改lts
为normal
:
# 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=normal
保存文件,然后退出。

我并不是说这是首选解决方案,只是说这是我所做的。我进入 /etc/apt/sources.list 并将所有标有 Wiley 的内容转换为 xenial。当我sudo apt -get update
再次运行时,我得到了新的软件包。我进行了升级,现在我的机器上有 16.04。
