无法在Alpine Docker映像中安装keepalived 2.0.20

Question

我正在尝试在Alpine Linux中使用Keepalived版本2.0.20-r0构建Docker映像。当我尝试安装时，得到以下信息：

$ docker run -it alpine:3.11
/ # apk add --no-cache keepalived==2.0.20-r0
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:
  keepalived-2.0.19-r0:
    breaks: world[keepalived=2.0.20-r0]
/ #

它曾经与Keepalived的2.0.11-r0版一起使用，但现在似乎已损坏。
有任何解决方法的想法吗？

如果我未指定版本，则它将安装2.0.19-r0。

/ # apk add --no-cache keepalived
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/main/x86_64/APKINDEX.tar.gz
