Tomcat7 missing after bbb-demo removal #73

Open ak4t0sh opened 5 years ago

ak4t0sh commented 5 years ago

I have strange dependency issue while trying to install xenial-220-beta (currently 220-beta-20) on ubuntu 16.04 using bbb-install.sh :

$ wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-220-beta -s bbb.example.com -e myemail@example.com

=> BBB works fine

$ apt purge bbb-demo Reading package lists... Done Building dependency tree
Reading state information... Done The following packages were automatically installed and are no longer required: authbind libcommons-collections3-java libcommons-dbcp-java libcommons-pool-java libecj-java libservlet3.0-java libtomcat7-java tomcat7 tomcat7-common Use 'apt autoremove' to remove them. The following packages will be REMOVED: bbb-demo* 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. After this operation, 1,986 kB disk space will be freed. Do you want to continue?

Purging configuration files for bbb-demo (1:2.2.0-9) ... root@bbb:~# bbb-conf --restart

=> BBB works fine

But if an apt autoremove is launched tomcat7 is removed and BBB do not running correctly

Workaround : do not install bbb-demo at all I have tried using PR #64 it works perfectly :)

Thanks for pointing this out. It looks like with tomcat7 removed, there is a check in

https://github.com/bigbluebutton/bigbluebutton/blob/master/bigbluebutton-config/bin/bbb-conf#L336

that looks to see if tomcat7 is still installed by checking if it's installation directory exists

    if [ -d $TOMCAT_DIR ]; then
      TOMCAT_SERVICE=$TOMCAT_USER
    fi

This logic is in correct because the directory /var/lib/tomcat7 probably still exists. If you have uninstalled tomcat7 and remove $TOMCAT_SERVICE from

https://github.com/bigbluebutton/bigbluebutton/blob/master/bigbluebutton-config/bin/bbb-conf#L392

You should have sudo bbb-conf --restart exiting without error. We'll fix this properly in the next update to BigBlueButton 2.2-beta.

This problem still exists on BigBlueButton 2.2.20. Purging bbb-demo marks tomcat7 as not required anymore, the next apt autoremove removes it and bbb throws errors about missing tomcat7.

In such a case you can mark the package as manually installed before you purge bbb-demo. First look after the correct version of tomcat to keep. Finally mark the package (in your case tomcat7) as manually installed:

apt show bbb-demo | grep -e "^Depends:"
apt-mark manual tomcat7

Current versions of BigBlueButton use a different directory path and need Tomcat for API demo only, hence its de-installation with the API demo should be no problem anymore.

@ffdixon I'm seeing this issue on 2.5.0-rc3 Steps to reproduce:

# Error: Detected some processes have not started correctly # # tomcat9 ———————————————► [✘ - inactive] #
