如何恢复发布升级？

我通过 ssh 从 13.04 升级到 13.10（没有使用）。当脚本即将删除过时的软件包screen时，我的 ssh 连接中断。现在，当我重新连接并运行它时，它只会显示。如何完成升级过程？do-release-upgradeNo new release found

答案1

跑步

sudo dpkg --configure -a

然后：

sudo apt-get dist-upgrade

最后运行（可能不需要）：

sudo apt-get upgrade

答案2

do-release-upgrade保存有关升级期间采取的所有操作的日志文件，其中还有/var/log/dist-upgrade其他可能相关的日志。/var/log/apt/var/log/dpkg

您能检查 /etc/update-manager/release-upgrades 并查看它是否设置为“prompt=never”吗？

我遇到了一个问题，我继承的旧服务器没有接收到新的 LTS 版本可用这一事实。这就是我修复它的方法。

例子：

$ sudo 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=lts
