从 18.04.1 (bionic) 升级到 18.10 (cosmic) 失败

我尝试使用软件更新程序进行升级，但下载文件后升级窗口默默关闭。然后我尝试使用 进行升级，do-release-upgrade但也失败了，没有出现明显的错误消息。

我安装了所有更新并重新启动，然后尝试升级。我还应该检查什么？

答案1

您的空间情况如何？据我所知，18.10 本身就是一次操作系统更新失败。内核的恐慌程度比一栋挤满了毒贩的房子还要严重，毒贩们的前窗闪烁着灯光。最好的建议是坚持使用您目前拥有的东西。否则，请运行检查以查找损坏的软件包，并验证它们是否确实都是正常工作且匹配的依赖项。如果升级失败，它应该会给出一个错误。如果它只是在重启后挂起，我发现让它继续加载的唯一方法是通过 alt-ctrl-f2 切换到另一个会话，然后使用 alt-ctrl-f1 返回以取消等待加载。
