上周四我更新了 Arch Linux 安装，周五重新启动时我的系统出现了多个问题。我是 Arch Linux（或一般的 Linux）社区的新手，不知道我可以尝试哪些事情来让它再次工作。
大多数应用程序以及网络将无法启动。我使用 KDE Plasma 作为 GUI 管理器。当我点击菜单时，我得到：
file:///usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/Kickoff.qml:19:1: plugin cannot be loaded for module "org.kde.plasma.private.kicker": Cannot load library /usr/lib/qt/qml/org/kde/plasma/private/kicker/libkickerplugin.so: (libicui18n.so.73: cannot open shared object file: No such file or directory)
当我检查插件时，pacman -Qo /usr/lib/qt/qml/org/kde/plasma/private/kicker/libkickerplugin.so我得到：
pacman: symbol lookup error: /usr/lib/libcurl.so.4: undefined symbol: libssh2_session_set_read_timeout
继论坛帖子我检查了我的安装ls -l /usr/lib/libssh*
lrwxrwxrwx 1 root root 16 Nov 1 2022 /usr/lib/libssh2.so -> libssh2.so.1.0.1
lrwxrwxrwx 1 root root 16 Nov 1 2022 /usr/lib/libssh2.so.1 -> libssh2.so.1.0.1

-rwxr-xr-x 1 root root 445776 May 4 14:43 /usr/lib/libssh.so.4.9.5
（与同事拥有的相同）
检查状态时sudo systenctl status NetworkManager.service我得到以下输出：

所以我认为有问题libcurl
我尝试设置网络但无济于事：

但ip link set <Network> up它什么也没做。
我尝试使用snapper重置到更新之前的版本：

但sudo snapper rollback 1828没有帮助。
我还可以尝试什么？请尽可能详细或提供链接，因为我是新手。
我无法创建 Arch Linux 论坛用户，因为我无法使用损坏的系统解决验证码问题...
答案1
希望还不算太晚。我遇到和你一样的错误
/usr/lib/libcurl.so.4：未定义符号：libssh2_session_set_read_timeout
事实证明他们在高版本的 libssh2 中添加了一个新标签 libssh2_session_set_timeout
我猜你不小心更新了你的curl，它依赖于带有标签的高版本libssh2，而你系统中的libssh2仍然是旧版本。
我所做的是我编译了一个新的libssh2在一个新的目录中，备份系统中的旧libssh2并将新编译的libssh2移动到/usr/lib中（2个lib文件，libssh2.so.1 libssh2.so.1.0.1），它解决了我的问题。
