Situation
You have Nextcloud HanssonIT stuck on version 23.0.12. The version is not maintained anymore. You want to upgrade but the UI doesn’t give you any more choice to upgrade. A further complication is the operating system is Ubuntu 20.04 but it’s the year 2024. So you’re 4 years behind on Ubuntu LTS as well.

Upgrade from Ubuntu 20.04 to 22.04
When working with Ubuntu or Debian in general, you always want to update first. So do this:
sudo apt update && sudo apt upgrade
Now reboot.
This doesn’t upgrade the distribution in site of the “upgrade” word present. After reboot, do this:
do-release-upgrade Checking for a new Ubuntu release Please install all available updates for your release before upgrading.
Basically you have “held” package and you have to remove them. In our case we had to remove a ton of PHP 7.4 packages:
apt -y --allow-change-held-packages php7.4-common apt -y --allow-change-held-packages php7.4-zip apt -y --allow-change-held-packages php7.4-opcache apt -y --allow-change-held-packages php7.4-cli apt -y --allow-change-held-packages php7.4-dev apt -y --allow-change-held-packages php7.4-fpm apt -y --allow-change-held-packages php7.4-cli apt -y --allow-change-held-packages php7.4-imagick apt -y --allow-change-held-packages php7.4-* apt -y --allow-change-held-packages php-pear apt -y --allow-change-held-packages php-7.4-xml apt -y --allow-change-held-packages php7.4-xml apt -y --allow-change-held-packages php7.4-bcmath apt -y --allow-change-held-packages php7.4-bz2 apt -y --allow-change-held-packages remove php7.4-bz2 apt -y --allow-change-held-packages remove php7.4-cli apt -y --allow-change-held-packages remove php-cli apt -y --allow-change-held-packages remove php-imagick apt -y --allow-change-held-packages remove php7.4-soap apt -y --allow-change-held-packages remove php7.4-cli apt -y --allow-change-held-packages remove php7.4-common apt -y --allow-change-held-packages remove php7.4-gmp apt -y --allow-change-held-packages remove php7.4-imap apt -y --allow-change-held-packages remove php7.4-mbstring apt -y --allow-change-held-packages remove php7.4-opcache apt -y --allow-change-held-packages remove php7.4-mbstring apt -y --allow-change-held-packages remove php7.4-readline apt -y --allow-change-held-packages remove php7.4-pgsql apt -y --allow-change-held-packages remove php7.4-ldap apt -y --allow-change-held-packages remove php7.4-json apt -y --allow-change-held-packages remove php7.4-intl apt -y --allow-change-held-packages remove php7.4-gd apt -y --allow-change-held-packages remove php7.4-curl apt -y --allow-change-held-packages remove php7.4-common
After this we could do this again:
do-release-upgrade
Next, because you’ve completely removed PHP, you’ll end up in this situation:
root@example:~# bash /var/scripts/update.sh sudo: php: command not found /var/scripts/nextcloud_update.sh: line 76: pecl: command not found sudo: php: command not found ... sudo: php: command not found The notifications app isn't enabled - unable to send notifications Fetching latest packages with apt... [⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻⣾⣽⣻]
I’ve omitted some of the output but further down, and after having trying to install PHP 8.1, I decided to move to PHP 8.3.
apt install curl gpg gnupg2 software-properties-common ca-certificates apt-transport-https lsb-release -y add-apt-repository ppa:ondrej/php apt update -uy apt -y install php8.3 history apt install php-pear
After this, redis.so became a problem so we did this:
cd /tmp git clone https://github.com/phpredis/phpredis.git cd phpredis phpize [apt install php-dev] ./configure make && make install
Then we had to do this:
apt install php8.3-fpm
We got a lot of this:
root@server:~# bash /var/scripts/update.sh The notifications app isn't enabled - unable to send notifications
Then we got this:
ERROR: The following modules depend on mpm_prefork and need to be disabled first: php8.3 Considering conflict mpm_worker for mpm_event: Considering conflict mpm_prefork for mpm_event: ERROR: Module mpm_prefork is enabled - cannot proceed due to conflicts. It needs to be disabled first!
Some more dependency problems:
a2dismod php8.3 a2dismod mpm_prefork
After another 40 minutes of trying, we decide to upgrade to Ubuntu 24.04, but quickly abandon that too due to the error below:
# do-release-upgrade Checking for a new Ubuntu release There is no development version of an LTS available. To upgrade to the latest non-LTS development release set Prompt=normal in /etc/update-manager/release-upgrades. root@nextcloud:~# mc -e /etc/update-manager/release-upgrades
This was aborted because:
https://docs.nextcloud.com/server/latest/admin_manual/installation/system_requirements.html
After much more troubleshooting, this:
[Tue Aug 13 11:16:16.155143 2024] [ssl:emerg] [pid 37210] AH02407: "SSLOpenSSLConfCmd DHParameters /etc/letsencrypt/live/site.example.com/dhparam.pem" failed for site.example.com:443
Commented out that line, then got this:
Your current version is still not compatible with the version required to run this script.

Conclusion
