一次 polkit 包升级导致的滚挂问题

操作系统 ,

今天是 15 号，需要搭一个新的系统用来做测试，用了一直使用的脚本来安装后，出了问题，无法连接网络，报错信息大概是权限问题，后面重启或者其他操作也全部报错

翻看错误日志，发现是 polkit 这个服务起不来，重启也不行

➜  ~ sudo systemctl restart polkit
Job for polkit.service failed because the control process exited with error code.
See "systemctl status polkit.service" and "journalctl -xeu polkit.service" for details.

再看包更新日志，确实更新了这个包，从 125 升到了 126

➜  ~ pacman -Q | grep polkit
polkit 126-1

怎么办呢？回滚

Arch 这个系统好就好在滚挂了能很快在 archive 里找到旧包

直接下载 125 版本的下来重新安装，然后重启服务，好了

不信邪，我测试机比较多，在另一台机上面滚一下重启，没有问题

难道新安装的系统有问题，旧系统升级就没问题？再来重试一遍系统安装，果然又有问题

得出结论，直接全新安装 126 包是会挂的，但是从 125 升到 126 就正常

更新：当天晚些时候，看到官方已经出了个补丁包，我试了重新安装系统测试，也是能正常了

总算明白，当时上网查这个错误怎么解决的时候，有人说，重新安装这个包解决了他的问题

我告诉你，重新安装是解决不了的，你重新安装的是打了补丁的了，包名一样，造成了你的假象
