What i need to do exactly

I don’t see any file lib/private/DB/AdapterPgSql.php

root@cloud:/# cd lib
root@cloud:/lib# ls
bridge-utils discover init libhandle.so.1.0.3 lsb security terminfo
console-setup firmware klibc-k3La8MUnuzHQ0_kG8hokcGAC0PA.so libxtables.so.10 modprobe.d systemd udev
cpp ifupdown libhandle.so.1 libxtables.so.10.0.0 modules sysvinit x86_64-linux-gnu

Same error in my system.
I hope this is the file you can find
univention-app shell nextcloud
cd /var/www/html/lib/private/DB

That’s all of my knowledge

root@cloud:~# cd /var/www/html/lib/private/DB
-bash: cd: /var/www/html/lib/private/DB: No such file or directory

i don’t have this folder thanks for your help !

First go into the docker with
root@meinserver:~# univention-app shell nextcloud
Than
root@nextc-05820453:/# cd /var/www/html/lib/private/DB

ok ive found it but what exactly i need to do to solve the problem
