now I installed it. And I see this message

File was saved in /tmp/userdata.inc.php, please move to /var/www/html/froxlor/lib/.

 

I saw a similar issue in the forum and you provided this solution

mv /tmp/userdata.inc.php /var/www/froxlor/lib

But it doesn't work with me ubuntu and apache and it says

mv /tmp/userdata.inc.php /var/www/froxlor/lib
mv: cannot stat '/tmp/userdata.inc.php': No such file or directory
 

despite it was saved in that directory

 

If the file.is really saved there, you as root should be able to copy it - to avoid that extra step, just chown your Froxlor directory with www-data user

something like this?

sudo chown www-data:www-data <froxlor>
sudo chmod g+w <froxlor>

the syntax is not valid

I tried chown froxlor /www-data too without success

I did check the chown help

and wrote chown root /froxlor

without success
 

chown -R www-data:www-data /var/www/froxlor

Thank you for your patience. I tried but it says

chown -R www-data:www-data /var/www/froxlor
chown: cannot access '/var/www/froxlor': No such file or directory
 

Well where did you install froxlor to? That's something you should know instead of blindly copy'n'pasting and running commands posted here

the installation folder was froxlor and we can even see the installation window using that folder 

so I thought to see the files there.

Also, considering I have already insalled it why it still shows the froxlor installation window 

http://185.181.9.139/froxlor/

Well you did not copy the lib/userdata.inc.php file as stated thus froxlor does not know about its database hence installation.

Please just follow the installation manual in our wiki, it's all in there and if followed correctly you will not have any issues

Just to be sure I'm on the right path - I'm on it.

https://github.com/Froxlor/Froxlor/wiki/Install-froxlor-on-ubuntu

That is correct, now did you especially follow part 4? And then as said from part 3 on in the tarball wiki entry? -> https://github.com/Froxlor/Froxlor/wiki/Install-froxlor-from-tarball

Also, be SURE the ubuntu package set the ownership correctly to www-data for /var/www/froxlor if not done already

I wasn't on it. I'm on it. I mean I'm installing it. 

I understand the last parts are my issues. Let's see it. 

For instance thank you very much for your support.

following step by step https://github.com/Froxlor/Froxlor/wiki/Install-froxlor-on-ubuntu 

and https://github.com/Froxlor/Froxlor/wiki/Install-froxlor-from-tarball

 

At the end of everything I come back to the same error message:

Could not create /var/www/html/froxlor/lib/userdata.inc.php, please create it manually with the following content

 

at same the chown command seems does not fix this issue

I'm ready to create it manually if you suggest me a kind of tutorial (not tons of pages)

 

 

Then it's either the wrong user or you did something wrong with the chown.

Bs sure to use the user the Webserver runs as, otherwise it cannot create files or write to the directory. 

What do the following two commands output?

# ls -la /var/www/

# ps faux | grep apache

Okay, weird, that looks just fine, both are www-data. And you are sure you pointed the default vhost to /var/www/ instead of /var/www/html/? Because your standard index.html looks more like it points to /var/www/html - do you by any chance have /var/www/html/froxlor/? What's the ownership there? 

yes the main document root is /var/www/html/

user name and group name www-data

the permissions should be already set for this user

And I have that froxlor folder too

I did check the ownership with ls -l /var/www/html/froxlor/ but it provided me with the list of files
