gitlab 将公有项目改为私有项目失败

报错内容：改项目属性失败，报500错误 “Whoops, something went wrong on our end.”

1. 查找日志
   查找/var/log/gitlab/gitlab-rails/production.log ，对比执行过程，发现报错对应如下日志：
   OpenSSL::Cipher::CipherError ():

官方推荐这个命令 gitlab-ctl tail gitlab-rails

2. google 解决办法。相信我，大部分的问题别人都碰到过。

   https://gitlab.com/gitlab-org/gitlab-foss/-/issues/59413
   https://docs.gitlab.com/ee/raketasks/backup_restore.html#when-the-secrets-file-is-lost

进入DB控制台
[root@VM_1_17_centos ~]# gitlab-rails dbconsole
psql (10.7)
Type "help" for help.

# update 后面数字是项目id
gitlabhq_production=> UPDATE projects SET runners_token = null, runners_token_encrypted = null;
UPDATE 16
gitlabhq_production=> UPDATE namespaces SET runners_token = null, runners_token_encrypted = null;
UPDATE 33
gitlabhq_production=> UPDATE application_settings SET runners_registration_token_encrypted = null;
UPDATE 1
gitlabhq_production=> UPDATE ci_runners SET token = null, token_encrypted = null;
UPDATE 0

3. 执行完后，都不用重启服务，立马见效
