几个月来，我一直非常开心地在桌面上工作，直到昨天，活动栏中出现了红色警告标志。单击按钮，它要求我运行包管理器以查看出了什么问题，错误是：
E:Unable to parse package file /var/lib/apt/lists/la-mirrors.evowise.com_ubuntu_dists_bionic-backports_InRelease (1),
E:The package lists or status file could not be parsed or opened.
如果我尝试显示更新，则没有任何内容，安装更新会提供与上述相同的详细信息以及消息：
“无法加载软件包列表。这是一个严重的问题。请稍后再试。如果再次出现此问题，请向开发人员报告错误。”
我希望这是很容易解决的问题，任何帮助都将不胜感激。我真的不想丢失信息或无法使用我的桌面。我马上道歉，因为我太笨了，我身体不太好，这没有帮助，（不，这不是宿醉，运气太差了）。
我有 7.8GiB 内存
AMD Athlon ii x 2 220处理器 x 2
NVD9
Gnome 3.28.2
操作系统 64 位
磁盘 983.4GB
我已经查看过 la-mirrors 等是否存在问题，但没有发现任何错误报告，我不想让事情变得更糟。

如果有帮助的话我还可以提供其他日志文件吗？
如果有人能提供帮助，我再次诚挚地表示感谢。
此外，我该如何根据要求向开发人员报告此事？
干杯
答案1
感谢 da_kingpin 为我指明正确的方向，并感谢 IKE 当天给出的原始答案。
“尝试 sudo rm -r /var/lib/apt/lists/*，然后再次运行 sudo apt-get update。”
然后我就可以使用软件更新程序了，一切都很好！
非常感谢，我无法形容这是一种多么大的解脱，欢呼。
