Can't Install Chamilo on Server

[mmoorefpcs]

I will start out by saying that I suspect that this issue is caused by something small that I just don't see.

I had Chamilo installed on the server previously. (1.11.14). PHP 7.3 I recently updated to PHP 7.4

Now, in order to even install 7.4 at this time, I had to add some repositories. I did have 7.4 installed on my machine back when 7.4 was supported, but I did not have all the packages that I needed and now you can't get them from the same repositories, so I had to add new ones. These repositories are listed on a few sites as the ones to add if you need older versions of PHP on an older box.

sudo add-apt-repository ppa:sergey-dryabzhinsky/php74
sudo add-apt-repository ppa:sergey-dryabzhinsky/php7-modules
sudo add-apt-repository ppa:sergey-dryabzhinsky/backports
sudo add-apt-repository ppa:sergey-dryabzhinsky/packages

Then Chamilo would not load. It was giving a database error. I decided to do reinstall and realized that pdo_mysql was missing after update. That was an easy fix. However, no matter what I tried after installing pdo_mysql, I get Fatal Exceptions on the last step of the install. I can't help but think there is a component missing from PHP or something like that, but I am unable to determine what that may be. As far as I can tell, my previous folder installation would still work if the database was intact. I let it get overridden because there was really nothing there.

Currently, running Ubuntu 18 on 32 bit Linux with 4GB of ram. Recently signed up for Ubuntu Pro to get additional security updates. If Ubuntu 18 is a problem for newer versions, that's fine, but I still should have been able to install the version that worked previously. I could not. When I tried I received an error similar to the one below.

I have done some searching, but I have not been able to find an error quite like this one.
I am in the process of building a 64 bit Ubuntu box, but there is another program that I use for my HOA that I need to make sure works with PHP 8 before I fully commit to that.

I even went as far as to install Composer version 2 to recreate the vendor directory (found that step somewhere online)

This is the error message that I get during step 7 of Chamilo installation:

I have re-downloaded the tar.gz file from Chamilo.org. I am still getting an error message, but it is a slightly different one.

I ran composer dump-autoload, and now I am back to the original error message.

[mmoorefpcs]

I found something that may shed some light on my particular issue. This post( issue 3710) describes an issue with two missing PHP packages: tokenizer and filter. I do remember an error that I was encountering that I was able to solve by installing php-tokenizer after the upgrade from 7.3 to 74. The error listed in issue 3710 is very similar to what I remember: "Fatal error: Uncaught Error: Call to undefined function token_get_all()". This error did go away after I installed tokenizer. However, I am unable to find a specific php-filter package in 2024 for the php74 that I have installed on my machine. It is listed as a module, so perhaps it's just a matter of making sure it is activated.

#3710

Tokenizer is installled:
php74-mod-tokenizer/bionic,now 7.4.33-0sergeyd6.118.04.1 i386 [installed,automatic]
php74p-mod-tokenizer/bionic,now 7.4.33-0sergeyd6.118.04.1 all [installed]

Side note: I installed a 32bit wampserver on my Windows laptop. Chamilo installed on that just fine. Now I just may need some help figuring out what is going on with my server.

I found an old export of the original database that I had forgotten about, and I was able to restore my 1.11.14 installation, and I was able to load the home page. As soon as I logged in, however, the screen went blank. The error message in the logs is very similar to the message I got during the failed installations. I should mention that these messages also appear in the logs during the failed installations. I have also purged other versions of php from my system. I had 5.6, 7.0 7.2,7.3,7.4 and this alternative php74 from the other repository.

The system is working now. I do not understand how, as I have not made any additional changes other than to recreate my certificates with letsencrypt. In any event, maybe something here will give a hint towards another problem in the future.

[mmoorefpcs]

The very next day the error came back.

Hi @mmoorefpcs
Sorry for the late reply, I only come around the discussions from time to time.
Ubuntu 18 should be OK as long as you have PHP 7.4, but I don't see why 32bit (I suppose it's one of your requirements). Not sure if this could be a problem but I don't think it should.

For Ubuntu, I would recommend ondrej's repositories (you can find that by yourself).

From the error messages you are reporting, it feels like you are trying (maybe) to update through Git. If you do that, you have to run composer update on your new Chamilo codebase. That will update your PHP dependencies, update the autoload files, and clean the cache.
Then I would make sure the app/cache, app/home, app/courses and app/upload are all writeable by the web server (on Ubuntu, sudo chown -R www-data: app/cache app/home app/courses app/upload should be OK).
And I would assume this would work.

I think the issue you are having should be solved by that. It seems like some code is looking for an Entity and not finding it. New entities are pre-configured into the autoload files through composer update (actually, this command does many things, which include composer dump-autoload which updates the autoload files). Once the new entities are registered in the autoload files, all Chamilo code can find these entities straight away (here your error messages say it cannot find them).
