What I have done so far:

1. reinstalled php:

# apt remove --purge php*
# apt install php-bcmath php-common php-fpm php-igbinary php-redis php-smbclient php7.3 php7.3-bcmath php7.3-bz2 php7.3-cli php7.3-common php7.3-curl php7.3-fpm php7.3-gd php7.3-gmp php7.3-intl php7.3-json php7.3-ldap php7.3-mbstring php7.3-mysql php7.3-opcache php7.3-readline php7.3-xml php7.3-zip

now the error page changed to the license header

2. changed the socket names as proposed here:

# echo "unixsocket /run/redis/redis.sock" >> /etc/redis/redis.conf
# echo "unixsocketperm 777" >> /etc/redis/redis.conf

Redis server

But I still get

RedisException: No such file or directory in /var/www/nextcloud/lib/private/RedisFactory.php:92

[leba]

yeah: progress: I changed the entry in /var/www/nextcloud/config/config.php to

'redis' => array ( 'host' => '/run/redis/redis.sock',

# systemctl restart redis-server.service 
# systemctl restart php7.3-fpm.service
# systemctl restart apache2.service
# systemctl restart nextcloud-domain.service

now, my ncp is up and running also due to the ncp-repor:

I run ncp-update and updated successfully to NextCloudPi version v1.47.0.
But I get an error updating to v1.48:

A dependency job for notify_push.service failed. See 'journalctl -xe' for details.
Error while applying update 1.48.2. Exiting...

@leba

A dependency job for notify_push.service failed.

Unfortuantely I don’t know what to do to fix it for you but I did find some relevant articles that perhaps have the answer for you?

Does the notify_push test work for you in CLI?

ncc notify_push:self-test

If you restart the notify_push service and/or start it manually does it start up then?

systemctl restart notify_push

systemctl start notify_push.service
service notify_push restart

Apperently there seem to be some problems with notify_push:

1. The log from hokkaido shows that the permissions of the notify_push Binary are wrong. Change them to sudo chmod a+x notify_push
2. Even then, the tip of inserting After=mariadb.service into /etc/systemd/system/notify_push.service seems to be necessary
3. The binary seems to have problems with 64 Bit OS (here: Ubuntu 22.04 64 Bit
   Adding the packets
   sudo apt install binfmt-support qemu qemu-user-static
   show relief

Also, what does the journalctl -xe say?

thank you very much. Unfortunately, nothing did help me, and I decided to start all over.
