Odd, I tested this by copying the update_script() (removing the things that are not needed) but the suwayomi-server keeps looking for openjdk-21-jre even with temurin-21-jre installed. Had to do the equivs magic to get around it.

update_script()

#!/bin/bash

if dpkg -l | grep -q "openjdk-17-jre"; then
    apt-get remove -y openjdk-17-jre
    mkdir -p /etc/apt/keyrings
    curl -fsSL "https://packages.adoptium.net/artifactory/api/gpg/key/public" | gpg --dearmor >/etc/apt/trusted.gpg.d/adoptium.gpg
    echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" >/etc/apt/sources.list.d/adoptium.list
    apt-get update
    apt-get install -y temurin-21-jre
fi
RELEASE=$(curl -fsSL https://api.github.com/repos/Suwayomi/Suwayomi-Server/releases/latest | grep "tag_name" | awk '{print substr($2, 2, length($2)-3) }')
if [[ "${RELEASE}" != "$(cat /opt/suwayomi-server_version.txt)" ]] || [[ ! -f /opt/suwayomi-server_version.txt ]]; then
    systemctl stop suwayomi-server
    cd /tmp
    URL=$(curl -fsSL https://api.github.com/repos/Suwayomi/Suwayomi-Server/releases/latest | grep "browser_download_url" | awk '{print substr($2, 2, length($2)-2) }' | tail -n+2 | head -n 1)
    curl -fsSL "$URL" -o $(basename "$URL")
    dpkg -i /tmp/*.deb
    systemctl start suwayomi-server
    rm -f *.deb
    echo "${RELEASE}" >/opt/suwayomi-server_version.txt.txt
fi

adding dummy openjdk-21-jre

apt-get install -y equivs
mkdir -p /tmp/fakejdk && cd /tmp/fakejdk
equivs-control openjdk-21-jre
nano openjdk-21-jre

nano openjdk-21-jre then update to match

Section: misc
Priority: optional
Standards-Version: 3.9.2

Package: openjdk-21-jre
Depends: temurin-21-jre
Version: 21.0.0
Maintainer: Your Name <you@example.com>
Provides: openjdk-21-jre
Description: Dummy package for temurin-21-jre
 This package satisfies dependencies requiring openjdk-21-jre by pointing to temurin-21-jre.

then

equivs-build openjdk-21-jre
dpkg -i openjdk-21-jre_*.deb

Did I miss something?
