我最近将我的 ubuntu 服务器从 16.04 更新到 18.04，然后从 18.04 更新到 20.04。我设法升级到 20.04，但升级过程中出现了问题。现在根据我的研究和人们的说法，可能是损坏的软件包或残留文件导致了问题。我的 wp 网站上的两个插件显示未安装 curl，这就是我开始研究这个问题的地方。

答案1
@rem3on 根据您对该问题的评论之一判断，仍安装有旧版本的 php7.4-common。要安装 php-curl，您还需要安装 php7.4-curl。这又依赖于 php7.4-common。在 Ubuntu 20.04 中，php7.4-common 对应于 7.4.3-4ubuntu2.4。但已经安装了“竞争”的 php7.4-common，即 7.4.12-3+ubuntu16.04.1+deb.sury.org+1。这看起来像是适用于 Ubuntu 16.04 的 PHP 7.4。– Henning Kockerbeck 14 小时前
在另一篇文章中再次查看 Henning Kockerbeck 的回答，我运行了 sudo apt-get purge php7.4-common，然后运行“sudo apt install php php-cli php-fpm php-json php-common php-mysql php-zip php-gd php-mbstring php-curl php-xml php-pear php-bcmath”问题已经解决，我现在没有收到 curl 丢失错误。虽然这个问题已经解决，但我必须确保服务器没有混乱，我现在能做什么来确保一切正常。此外，可能还有比 curl 丢失更多的问题，你能帮我解决吗？
