我尝试在 Ubuntu 20.04 上安装 AnyDesk，并在 shell 中运行此命令 -
abhilash@friday:~$ sudo apt-get upgrade

我看到论坛上已经解决了此错误消息这里但是这个讨论对我没有帮助，因为我运行的 Ubuntu 没有双启动，并且没有任何可能导致该问题的防病毒软件（根据问题的讨论）。
由于该软件包linux-image-5.8.0-53-generic看起来与操作系统/内核有关，因此我没有对其进行过多的调整，但已经尝试了上面提到的所有方法https://itsfoss.com/dpkg-returned-an-error-code-1/但目前还没有任何进展。
我目前能够访问我的所有数据并且能够重新启动我的系统，但由于我无法安装新的软件包，所以我想解决这个问题。
期待社区的任何建议。
