When start the container nextcloud_aio_nextcloud,
It is very slow for step "Installing imagemagick via apk..."
and finally failed for "Installing PHP build dependencies..."

So add a proxy for the domain "dl-cdn.alpinelinux.org"
then it will be very quick, however get the failure below

Installing imagemagick via apk...
Installing PHP build dependencies...
WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.16/main: Permission denied
ERROR: unable to select packages:
Could not install build-deps!
Installing Imagick via PECL...
error: 'imagick' does not exist

Describe the solution you'd like

Search on the internet, seems there is solution below
RUN sed 's/https/http/g' -i /etc/apk/repositories
RUN apk update
RUN apk add --no-cache bash

Can we also add this in the startup.sh file before installing the php extensions ?
or some other better solution ? Thanks

This looks like a proxy issue on your side based on e.g. docker-library/openjdk#402 so you should rather fix this yourself. Also reducing the security is not something we will do.
