This is the error I'm facing
puppet version : 3.8.7 , Centos 7,
i tried tracing of db:rake
[root@ki /]# /usr/sbin/foreman-rake db:migrate --trace --verbose
rake aborted!
Errno::ENOENT: No such file or directory @ rb_sysopen - /opt/rh/sclo-ror42/root/usr/share/gems/gems/mail-2.6.1/lib/mail/../../VERSION

& i checked for VERSION file which was not there..
[root@ki mail-2.6.1]# pwd
/opt/rh/sclo-ror42/root/usr/share/gems/gems/mail-2.6.1
[root@ki mail-2.6.1]# find . -name "VERSION"
[root@ki mail-2.6.1]#

I think this is because of VERSION file missing, in mail gem?
I tried restarting postgres service, fqdn is good
host version is centos 7
I'm following installation guide .
