镜像越级升级导致NextCloud无法打开

     一般情形下,通过

docker pull nextcloud 

可以获取到最新的nextcloud容器镜像,然后nextcloud会自行更新到最新版本。

      由于我使用了一段时间nextcloud应该是在16这个版本,然后直接pull下来了18版本。此时,发现我的nextcloud无法打开,出现如下错误:

通过以下命令,查询到相关的版本

docker exec --user www-data nc php /var/www/html/occ status

结果


Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
  - installed: true
  - version: 18.0.1.3
  - versionstring: 18.0.1
  - edition:

通过以下命令进行升级

docker exec --user www-data nc php /var/www/html/occ upgrade

结果

发现不允许升级。

       修改以下这个文件 nextcloud/lib/private/Updater.php 镜像越级升级导致NextCloud无法打开_第1张图片

 修改保存之后,再次通过以下命令就可以升级

docker exec --user www-data nc php /var/www/html/occ upgrade

等待升级完成之后,使用以下命令关闭维护模式

docker exec --user www-data nc php /var/www/html/occ  maintenance:mode --off

结果

Nextcloud or one of the apps require upgrade - only a limited number of commands are available

You may use your browser or the occ upgrade command to do the upgrade
Maintenance mode disabled

完成以上步骤之后,重新打开网页即可进入到Nextcloud里面。

一句话忠告:尽量不要夸太多版本升级,否则会出现太多的异常无法解决
