It's an upstream issue tracked there

[alexbelgium]

Hi, relevant PR upstream that should fix it : nextcloud/server#44939

[alexbelgium]

Actually according to nextcloud/server#44685 the solution is on the configuration of nginx, so the correction should be made here (haven't found out yet how)

[alexbelgium]

Actually, solution is simply to disable fastcgi_param front_controller_active true in

docker-nextcloud/root/defaults/nginx/site-confs/default.conf.sample

Line 127 in f72ad27

fastcgi_param front_controller_active true; # Enable pretty urls

Do I need to do anything other than commenting this out? I have done it and restarted the docker. Still the same for me but now it is asking for the password before giving the same error.

you need to change it in

fastcgi_param front_controller_active true false

[dansity]

thank you, it should have been obvious. However the issue is still present to me even after setting it to false and restarting the docker.

edit: what worked for me is I went to the mysql database in adminer and changed the value in the oc_appconfig table from no to yes for the app I wanted.

how to ?

[Raphty]

@yzx1208 adminer is a tool with which you can fairly easily navigate through databases
https://hub.docker.com/_/adminer/

you connect to the database where you have you nextcloud tables and then open up the table list look for oc_appconfig and then navigate through the entries.

be careful! if you don't know what you are doing better don't!

I found this worked for me. Just edit default.conf, not the .sample file

PR is opened and waiting

[kesselb]

Some of those "This app cannot be enabled..." cases should be fixed by nextcloud/server#45765 which was released with 29.0.3.

Same error happens on fresh install of latest linuxserver nextcloud 30 docker compose container. Unable to enable any app through the web browser. Was able to enable it with the occ command.

This is right! Only occ... Apps has installed and work, but still marked in GUI as not installed.
For reference (in docker's container) some commands:
sudo occ list;
sudo occ app:enable files_external;
sudo occ app:install mail
