I want to compress Docebo files and folders in a tar.gz package and then upload it to
my web linux server and extract it there .
May this action cause to bad files and folders permission and cause to problems in installation or implement or security ?

I don't think it will create any problem, since creating a tarball should keep the permissions and, obviously, avoid bad files.
By the way, if you have permission problems, then you just have to reassing them properly, as described in the manuals.

Hi
Today I uploaded my tar.gz file and extracted it on server .
Now all files permission is 444 and all folders permission is
755 .
Are all permissions OK ?
I think 444 permission makes problems .

I think those permissions were inherited from the base settings of your system.
If you want to be sure that your installation works correctly, please apply the seetings shown in the manuals.
