Libretime: Problem: Apache error 500 in Ubuntu 18.04.1

[solohtml]

Hi folks, after installing LibreTime git version in my Virtualbox VM, I could access to final configuration, and all services seems to be working ok... So strange at first time in my earlier installs (16.04, Debian 9, ...)
BUT, then... Error 500 in my Apache server. and no log accesible...
Holly molly... Maybe my Apache is broken? I don't know...
Previous to the git installation I reviewed wiki pages and add PHP ppa's but triying without it error is the same...
what am I doing bad?

Is there nothing in /var/log/apache2/error.log at all?
It sounds like you may have an apache module missing. I had similar on an OVZ vps system where it had a very cut-down version of ubuntu. I had to add in some extra basic apache modules. But I forget which ones :\ mod_rewrite was one.
Try starting apache2 from the command line: sudo service apache2 restart
I expect it will give you clues as to the problem. Example mod_rewrite not installed or enabled

I'd suggest using 16.04 as we can't support 18.04 (see #580). Type php --version from the command line and see if you are using Php 7.0 or 7.1. The advice JohnnyC provides is good but since this is a support request for an unsupported version of Ubuntu I'm going to suggest that we close this issue and follow up on any conversation on the forum.

Well... Version installed seemed to be PHP 7.3... I'm actually downgrading it to PHP 7.0 to try compatibility, thanks for the advice.

Oh dear! At least now i have a logfile... Not corrected 500 error but maybe a million of errors at the same point.

I don't know... Better I wayback to 16.04 OS...

Rerunning the install just might work

I doubt it, it reinstalls PHP 7.2 ... Better 16.04 i think...

Yeah good point, we can modify the install for 18.04 to include PHP 7.0 vs. 7.2. And if you want to run 18.04 you can manually uninstall 7.3 and install 7.0 If you do this it should work but I can't provide exact steps.

If you use the command dpkg -l | grep 'php' and then sudo apt remove PACKAGENAME for every php7.2 or php7.3 version installed and then sudo apt install libapache2-mod-php7.0 php7.0 php-pear php7.0-gd php7.0-bcmath php7.0-mbstring php7.0-pgsql php7.0-curl php7.0-apcu it should work. My guess is that even though you installed the alternate php version it still had the older ones.

If you want to work on a PR for the install script specific to 18.04 we could help people who go down this route in the future avoid the same problem. Otherwise it'll have to wait until someone has the time.

It might also be important to do something like a PIN for version php7.0 to avoid upgrades in the future although I'm not sure. If it isn't too much trouble using 16.04 is probably a better idea until we do a transition to a new MVC but that could be a way off.

Closing this as it's a duplicate of #580
