更新Gitlab时遇到错误The following signatures were invalid

之前设置了Gitlab的自动更新定时任务，这一段时间发现没有成功执行。今天登陆到服务器看了一下，发现更新的时候报错了：

Err:36 https://packages.gitlab.com/gitlab/gitlab-ce/debian buster InRelease

原因是因为，gitlab的key过期了，解决方法：

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3F01618A51312F3F

其中，最后面跟着的字符串，就是key的ID。

然后再执行：

sudo apt update && sudo apt install gitlab-ce

就可以了。
