Question

当我apt upgrade时，我得到错误处理包错误：

我试过网上提到的常见解决方案。但它被困在了一个循环中。

You might want to run 'apt-get -f install' to correct these.

这让我们回到安装步骤。我如何解决这个问题并使用apt-get进行升级？

操作系统:Ubuntu16.04.7 LTS x86_64

Answer 1

您的…is locked by another process…很可能是由另一个正在运行的dpkg进程引起的。这可能会从以前失败的包配置运行中遗留下来。

如果您确实没有在另一个窗口中运行dpkg或apt等，请查看现有的dpkg进程，并考虑对它们进行kill处理。

$ ps awux | grep dpkg

至于其他错误，这都是由于一个或多个软件包在安装时未能进行配置造成的。如果没有看到实际发生的情况，就不可能找出原因。

如果您确定您不需要这些包，您可以删除它们，直到问题消失。如果由于rm前或后rm脚本中的问题，即使删除包也失败了，您可以在/var/lib/dpkg/info/中找到这些脚本，例如/var/lib/dpkg/info/mysql-server.postrm，并删除它们。显然，这是“核选择”，如果你想把这些包裹留在身边，那是不可取的。如果你要立即重新安装它们的话，应该没问题。

我不推荐你所追求的大规模清除策略。这是太容易删除一些重要的和完全破坏你的安装。集中精力解决单个软件包的安装问题。apt的输出善于告诉你什么取决于什么。按照依赖项来纠正这一点。

为了帮助解决未来的问题，保存安装故障日志。我们无法提供适当的帮助，因为我们无法理解为什么这些包一开始就无法配置。

Answer 2

也有这个问题。最后，我的引导分区已满到最后一个字节。一些旧的更新没有被正确删除。手动删除较大和较旧的文件，并重新启动。再起作用

要检查您的(引导)分区大小，请使用像"baobab“https://linux.die.net/man/1/baobab这样的工具。

！在删除文件前，请检查文件名！你可能会搞砸你的系统
