I’m using Ubuntu 16.04 and recently upgraded the server to php7.3 from php7.0 but then was unable to open any libretime pages (Ooops something went wrong).

I note on github that php7.2/7.3 support is quoted on ubuntu 18.04, is there an issue running php7.3 on 16.04? Do I need to re-run the installer or should it ‘just work’ ? Thanks.

Can someone please help me debug this a bit further? Under php 7.3, all the airtime services are running but the webpages can’t be generated;

`Airtime Liquidsoap Service`  
` Loaded: loaded (/etc/systemd/system/airtime-liquidsoap.service; enabled; vendor preset: enabled)`

also

`airtime-playout[18719]: 2020-06-11 11:00:32,338 [api_client] [INFO] Unable to get Airtime API version number.`

apache log looks like this;

`ip.addres - - [11/Jun/2020:11:21:57 +0100] "GET /api/get-stream-setting/format/json/api_key/CEEMCRK ******** EN2BK/ HTTP/1.1" 500 4164 "-" "Python-urllib/2.7"`

no errors are generated in the apache2 error.log, at rest or at login. Downgrading from php7.3 to 7.0 and airtime works again, no services needed restarting 🤔

Please let me know what other logs you want to see…

Re-running the installer with php7.3 enabled doesn’t seem to make a difference to the installer… it’s checking for php7.0 files…

`php7.0 is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).`  
`php7.0-curl is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).`  
`php7.0-gd is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).`  
`php7.0-pgsql is already the newest version (7.0.33-29+ubuntu16.04.1+deb.sury.org+1).`

OK, simple environment error… zendphp.log \> `Unable to open PDO connection [wrapped: could not find driver]`  
Comparing info.php for both versions, in php7.0 I have;  
`PDO drivers|mysql, pgsql`  
in php7.3 I have;  
`PDO drivers|mysql`  
Installing the missing pgsql driver  
`sudo apt install php7.3-pgsql`  
fixed it up and everything worked immediately. I hope this helps someone else 🙂
