之前同事一键部署的jumpserver，版本是2.10.2。由于这个版本有重大漏洞，决定升级到2.28.20。
升级过程中有报错，提示找不到jumpserver/mysql:5.7，但是实际镜像是jumpserver/mysql:5，具体执行报错如下，请教各位大神，应该如何处理？
[root@ygxb_rrx_0_209 jumpserver-offline-installer-v2.28.20-amd64]# ./jmsctl.sh upgrade
Are you sure you want to update the current version to v2.28.20 ? (y/n) (default y): y
