一个月前我升级到了 Ubuntu 22.04，升级过程中出现了一些错误，但最终还是完成了。但从那以后我就无法运行 sudo apt upgrade 了。它出现了五个无法创建某些图标的备份链接的错误。
每次我尝试 sudo apt upgrade 时，都会显示类似于下面的错误。（我无法重现确切的错误，因为我尝试删除并重新安装 aptdaemon-data 包）

我尝试检查标志，结果显示如下

尽管如此，我尝试运行 chattr，但它也不起作用
sudo chattr -ia /usr/share/icons/hicolor/24x24/status/aptdaemon-cleanup.png
chattr: Operation not supported while setting flags on /usr/share/icons/hicolor/24x24/status/aptdaemon-cleanup.png
我卸载并从 livecd 启动并运行 fsck，也没有显示任何错误。
我尝试以 root 身份sudo su运行 apt upgrade 命令，但出现了同样的错误。
我尝试删除 aptdaemon-data 包，这个包成功了，但之后我就无法再安装它了。我试了一下，sudo apt upgrade结果显示有些包被阻止了。我运行sudo apt dist-upgrade并安装了这些包。现在 apt 说我的系统是最新的。
现在，当我尝试安装 aptdaemon-data 包时，apt 显示上述错误unable to make backup link of './usr/share/icons/hicolor/24x24/status/aptdaemon-cleanup.png' before installing new version: Operation not permitted
此时，我不确定该怎么做，我不知道这个 aptdaemon-data 包是否重要，或者如果没有它我是否可以继续。我不知道这是否会影响未来的更新。任何关于此问题或如何修复该错误的意见都将不胜感激。
我觉得不对劲，图标目录中有一个文件无法以任何方式删除或编辑，即使我是 root 身份。

这很少见。嗯。你先试了一遍，然后又试了sudo apt-get install -f一遍sudo apt update ，或者sudo apt upgrade下载sudo apt dist-upgrade
.deb 文件。aptdaemon .deb 看看会发生什么！
