Sorry was on a weekend doing furniture building...

Weird one. I will investigate.
In the mean time you don't necessarily need to do php artisan key:generate
You can also generate the APP_KEY with echo "base64:$(openssl rand -base64 32)" and set it here (without the < >)
APP_KEY=base64:<result of 'openssl rand -base64 32'> in your .env

[ildyria]

Also what are the php extensions that you have installed ?

[ildyria]

I do not see bcmath, I do not see ldap in the phpinfo you gave me.

Please double check the server requirements: https://lycheeorg.dev/docs/installation.html#server-requirements

[ildyria]

I will need to double check the config_manager error locally.

[adryb]

I missed these two.

Installer showed

[ildyria]

No worries ! Great to hear progress on your side. It just highlight that maybe I should add a small check script for requirement configuration. It is annoying though that the installer does not work without all extensions for laravel... That needs to be improved. :(

[adryb]

Now i have error with redirection - look:

https://example.com/Lychee/public

[ildyria]

You are hosting Lychee on subfolder, this is really not the recommended way of doing it, a lot of people got issues with this kind of setup.
You will need to make sure that your
APP_URL=example.com
and
APP_DIR=/Lychee/public

The problem with this kind of setup is that it is crazy insecure as people can traverse all the other folders in Lychee...

[ildyria]

If you can join our discord and ping me, I will show you what I mean by crazy insecure, I do not want to expose those vulnerabilities in public. :|
