docker - Alpine :3.14 docker libtls.so.20 冲突

Question

所以我遇到了来自 alpine 的最新 docker build 的错误。 alpine:3.14.0 大约在一天前发布，并试图安装 libressl 和 libressl-dev，但两者似乎都失败并出现以下错误。我目前的工作是使用 alpine:3.12.0 进行构建，因为 3.12.0 似乎没有安装 libretls。虽然我想知道如何解决这个问题。我试图删除 libretls 但这没有用(下面也有错误)。谢谢

this是上游问题。降级到 alpine 3.13 暂时有效，直到问题得到解决。
通常 docker 镜像支持固定的 alpine 版本(感谢 MrGlass 评论)。例如

python:3-alpine -> python:3-alpine3.13
php:7.4-fpm-alpine -> php:7.4-fpm-alpine3.13
