符号查找误差gdbus

Question

继续得到这个错误：

/usr/bin/gdbus: symbol lookup error: /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0: undefined symbol: g_date_copy

看：

root@server-sl:~# ldd /usr/bin/gdbus

检查一下：

root@server-sl:~# ls -l /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0

    lrwxrwxrwx 1 root root 26 set 22 05:53 /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 -> libgobject-2.0.so.0.5800.1

我找不到出什么问题了。我在一个DebianLinux服务器上-sl 4.18.0-2-AMD 64 #1 SMP 4.18.10-2 (2018-11-02) x86_64 GNU/Linux

在从16.04升级到18.04之后，得到了类似的问题

还有一些问题，如ssh登录速度慢、dpkg和apt工作慢(在“处理触发器”期间，进程总是被塞了很长时间)。

解决办法太简单了：

ls -il /lib/x86_64-linux-gnu/libglib-2.0.so*
ls -il /usr/lib/x86_64-linux-gnu/libglib-2.0.so*

我遇到了一种情况

/lib/x86_64-linux-gnu/libglib-2.0.so.0 -> libglib-2.0.so.0.3200.4
/lib/x86_64-linux-gnu/libglib-2.0.so.0.3200.4

指向libglib-2.0.so.0.3200.4

/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0 -> libglib-2.0.so.0.5600.4
/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0.5600.4

指向较新的版本。

因此，解决方案是删除/lib/文件夹中的文件

rm /lib/x86_64-linux-gnu/libglib-2.0.so.0
rm /lib/x86_64-linux-gnu/libglib-2.0.so.0.3200.4
