Debian
由於 libc6 版本，無法升級 certbot
我正在嘗試使用 Python 2.7.9 將 Certbot 從 0.10.2 更新到支持 Debian 9.1 中的 ACME 2 的某個版本。

編輯：
所以顯然我已經在 Debian 9 中安裝了一些來自 Debian 10 的軟體包。因為我不能用 apt 做任何事情，所以我試圖用 aptitude 解決依賴關係。

終於找到了解決辦法：
apt install libc6/stretch libc6-dev/stretch libc-dev-bin/stretch libc-bin/stretch locales/stretch linux-libc-dev/stretch另一個使用者也有同樣的問題，幸運的是有人在這裡找到了解決方案。
我不建議混合和匹配適用於發行版不同主要版本的軟體包，因為有時會引入依賴關係，從而破壞整體。如果可能的話，我會在包源沒有混合的其他地方“重建”伺服器，因為 libc 是一件需要改變的主要事情……
正如其他人所建議的那樣，您是否可以在 docker 之類的東西中執行您的服務，以便每個人都可以擁有它想要的環境而不會污染主機的環境？這樣，如果事情發生橫向變化，您可以拆除容器並建構一個新的……
TLDR；我很擔心你的伺服器，因為聽起來你已經“越過了溪流”。
