接下来：
https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/6.x-or-7.x-to-7.6.md
我将gitlab从6.9升级到7.6，而unicorn和sidekiq现在拒绝启动：
Removing stale Unicorn web server pid. This is most likely caused by the web server crashing the last time it ran.
Starting both the GitLab Unicorn and Sidekiqmaster failed to start, check stderr log for details
.
The GitLab Unicorn web server is not running.
The GitLab Sidekiq job dispatcher with pid 5705 is running.
错误日志（unicorn.stderr.log和sidekiq.log）中的错误是undefined method 'attr_accessible' for UserTeam (call 'UserTeam.connection' to establish a connection):Class

我还必须将ruby从1.9.3升级到2.1.5，但在那里的任何步骤中都没有错误，在gems安装或db：migrate任务期间也没有错误。
