You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 linux-image-4.15.0-210-generic : Depends: linux-modules-4.15.0-210-generic but it is not going to be installed
 valgrind : Depends: libc6-dbg but it is not going to be installed
            Recommends: gdb but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution)

根据错误提示，安装Valgrind时出现了依赖关系问题。可以尝试使用以下命令解决：

sudo apt --fix-broken install

这个命令会尝试修复系统中的损坏或不完整的软件包，并满足软件包之间的依赖关系。

如果该命令无法解决问题，那么可以尝试更新软件源并再次安装Valgrind，具体命令如下：

sudo apt update
sudo apt install valgrind

ok搞定！
