无用的知识:apt upgrade时pkg.jenkins.io无法连接造成jenkins启动失败

时常需要给服务器打打补丁,执行apt update后执行apt upgrade,但是奇怪的是jenkins升级后就挂了。

没有改什么配置,没有增加什么新的应用。用apt remove jenkins再apt install jenkins也不行。

Setting up jenkins (2.263.1) ...

See "systemctl status jenkins.service" and "journalctl -xe" for details.

试过netstat -apn | grep 8080看端口占用,先是发现过阿里云盾,还以为是中毒了,用top看看cpu占用,不像。

把端口改成8888,也不行。

然后改天,直接执行apt update后执行apt upgrade就好了。原来就是pkg.jenkins.io不能连接造成的。

中间还曾经怀疑过java的问题,网上不少说是java没设置好或者缺少$JAVA_HOME的。并不解决我的问题。

再单独发一下jenkins状态的故障查询。
