查资料得知，GitLab发现报500错误，大意为DB数据关系错误，需要升级数据库关系。
查看数据库状态

sudo gitlab-rake db:migrate:status

发现有些显示为down了

   up     20190702173936  Populate remaining merge request assignees
   up     20190703130053  Remove gitaly feature flags
   up     20190703185326  Fix wrong pages access level
   up     20190709204413  Add rule type to approval project rules
   up     20190710151229  Add index to approval project rules rule type
   up     20190715114644  Drop project features pages access level default
  down    20190719122333  Add login recaptcha protection enabled to application settings
  down    20190816151221  Add active jobs limit to plans

再执行下面命令，升级数据库关系

gitlab-rake db:migrate
gitlab-ctl reconfigure 再加载

OK，错误解决
