继续出现此错误：

我找不到问题所在。我使用的是 DebianLinux server-sl 4.18.0-2-amd64 #1 SMP Debian 4.18.10-2 (2018-11-02) x86_64 GNU/Linux
答案1
从 16.04 升级到 18.04 后遇到类似问题
还遇到了 ssh 登录速度慢、dpkg 和 apt 工作速度慢等问题（在“处理触发器”期间进程总是卡住很长时间）
解决方案太简单了：
ls -il /lib/x86_64-linux-gnu/libglib-2.0.so*
ls -il /usr/lib/x86_64-linux-gnu/libglib-2.0.so*
我遇到了一个情况
/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 而
/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。
所以解决方案是删除 /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
