I'm making a php panel from which you can install apps like owncloud & plex on your server. I've created multiple bash scripts that install and remove software. I tested all of them from shell, everything works as it should. However, when I run the scripts from php as root using sudo on ubuntu 15.10, apt-get & dpkg are not working as they should.
In visudo I have:
seedbox ALL = (root) NOPASSWD: /bin/appinstaller
appinstaller is a bash script that run the install/uninstall apps bash scripts (e.g. appinstaller plex)
Plex script example:
dpkg --configure -a
cd /tmp
wget https://downloads.plex.tv/plex-media-server/0.9.15.6.1714-7be11e1/plexmediaserver_0.9.15.6.1714-7be11e1_amd64.deb
dpkg -i plexmediaserver_0.9.15.6.1714-7be11e1_amd64.deb
When I run appinstaller directly from bash everything works perfectly.
When I run appinstaller from php using (confirmed that script is running as root):
exec("sudo /bin/appinstaller plex > /home/installer.log 2>&1 &");
It works but I get apt & dpkg errors when I try to install other apps such as:
E: The package plexmediaserver needs to be reinstalled, but I can't find an archive for it. (even though it's installed and working)
And also dpkg --configure -a returns an error.
Plex is working fine, but seems like apt doesn't finish the installation process and gets stuck somewhere, also commands running after the apt-get install/dpkg won't run from php but will run from bash. I tried to run the script also from cron & systemctl and I get the same issue.
It's worth noting that some apps are installing/uninstalling without any issues.
What could be making the difference between running the script from php/cron/systemctl or from shell directly? Can I emulate normal bash session?
