I configured vpn server inside docker from this repo 10 months ago. But recently met connection errors. I found this issue and want to try fix it with downgrading libreswan to 4.15, but don't understand how to do it correctly inside Alpine Linux.
What i tried:
sudo docker exec -it ipsec-vpn-server bash
ipsec --version
Linux Libreswan 4.6 (XFRM) on 4.19.0-21-cloud-amd64
apk list libreswan
libreswan-4.6-r0 x86_64 {libreswan} (GPL-2.0-or-later) [installed]
apk del libreswan
OK: 40 MiB in 79 packages
apk update
fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/main/x86_64/APKINDEX.tar.gz fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/community/x86_64/APKINDEX.tar.gz v3.15.10-29-g9ff737c7902 [https://dl-cdn.alpinelinux.org/alpine/v3.15/main] v3.15.10-29-g9ff737c7902 [https://dl-cdn.alpinelinux.org/alpine/v3.15/community] OK: 15881 distinct packages available
ipsec restart

ipsec --version
Linux Libreswan 4.6 (XFRM) on 4.19.0-21-cloud-amd64
...Why is it still installed?
apk add libreswan=4.5
ERROR: unable to select packages:

Tell me please how to downgrade libreswan version inside docker Alpine
