【问题描述】：
我不得不终止会话，然后在我重新启动服务器之前无法访问数据库。
当我重新登录并发出“apt upgrade”时，我收到以下错误。
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
我运行“dpkg --configure -a”并得到以下内容，然后它就冻结了
Setting up mysql-server-8.0 (8.0.22-0ubuntu0.20.04.3) ...
mysqld will log errors to /var/log/mysql/error.log
mysqld is running as pid 86150
在另一个 tty 上 journalctl -xe 在升级冻结时给出这个。

当我重新启动并登录时，mysqld 正在运行
我已经尝试了以下方法。
# cp -r /etc/mysql /etc/mysql_old
# apt autoremove
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
# dpkg --configure -a
Setting up mysql-server-8.0 (8.0.22-0ubuntu0.20.04.3) ...
mysqld will log errors to /var/log/mysql/error.log
mysqld is running as pid 7451
我们又回到了这里。
如果我检查 mysql 进程，我发现没有进程 7451，但这是输出。

【问题讨论】：
-
你有多少数据？你从哪个版本升级？转换数据可能需要一些时间。另外，某些版本不能跳过，请查看升级手册。

我不确定我从什么升级，但现在是 8.0.22-0ubuntu0.20.04.3。我已经解决了这个问题，我认为数据库大小不是问题，我昨晚把它放在了一夜，它仍然挂在那里。
