DigitalOcean Droplet (Ubuntu 18.04) 密碼重設循環

Question

我對 DigitalOcean Droplet 比較陌生，但在開始遇到問題之前，我已經使用 Ubuntu 18.04 Droplet 運行 Nextcloud 實例幾週了。我不能 100% 確定問題出在哪裡，而且我的故障排除也沒有讓我走得太遠。

我錯誤地配置了其中一台 Nextcloud 客戶端計算機，導致它推送的文件超出了空間所能容納的數量。我的 Droplet 使用率為 100%，用戶端電腦無法連線到它。它可用於 SSH。

當我透過 SSH 連接到電腦或使用 DO 控制台時，系統會立即要求我更改 root 密碼。一旦更改成功，就會立即關閉連線。再次連接，它再次要求更改密碼 - 我陷入了循環。

SSH -vv 輸出：
