How can I solve NO_PUBKEY 1CC02413BFF88108 error?

apt-get update --allow-insecure-repositories;apt-get upgrade found some new packages: enchant libargon2-1 libgd3 libicu65 libidn2-0 libpcre2-8-0 libpcre3 libsodium23 libxml2 libzip4 libzstd1 php-common php-pear php7.3-igbinary php7.3-imagick php7.3-memcached php7.3-msgpack. Should I update it?

When I wrote apt install php7.4-bcmath php7.4-cli php7.4-common php7.4-curl php7.4-fpm php7.4-gd php7.4-gmp php7.4-igbinary php7.4-imagick php7.4-intl php7.4-json php7.4-mbstring php7.4-memcached php7.4-msgpack php7.4-mysql php7.4-opcache php7.4-readline php7.4-soap php7.4-xml php7.4-xmlrpc php7.4-zip it found non solved dependensy: php7.4-fpm depends on systemd but it will not be installed. So I can't upgrade to 7.4

It recommended for NextCloud

I'm running nextcloud on beowulf, with PHP 7.4.
The trick is that pkgs.tdrnetworks doesn't include everything, so you'll need packages.sury.org in your sources as well, i.e.

deb https://packages.sury.org/php/ buster main
deb https://pkgs.tdrnetworks.com/apt/devuan beowulf main

You'll likely also want something like:

Package: *
Pin: release o=deb.sury.org
Pin-Priority: 200

(or any priority lower than that assigned to tdrnetworks) in /etc/apt/preferences so the fixed packages take precedence, and stuff from sury.org is only pulled in if it doesn't exist elsewhere.
