arbtd: Package isn't signed with proper key

 If you are System Admin and worked on linux machine or servers in your current job or in past.

Chances are you might come across linux service abrtd, even if you have not worked on it. but might be through some other work.

same thing happened to me, while I was doing my regular work of installing php packages on linux servers, i came across this error for which spent couple of hours actually to resolve it. The error was 

abrtd: Package 'php53u-fpm' isn't signed with proper key

at that time I was new to linux servers and to this abrtd service (honestly speaking I still dont know much about abrtd service 😜)

But as it was part of job to find the solutions and apply the fixes and get the required packages installed on servers.

I came managed to solve the issue I faced couple of years back with below steps. Hope some of you might find it useful.

Small information about what is actually abrtd is automated bug reporting tool daemon on Linux.

If you are using CentOS then look for below file on your server (if you are using debian/ubuntu - locate or find configuration file for abrt on your machine or server

  • /etc/abrt/abrt-action-save-package-data.conf

You need to then use your favorite editor to edit the file and make changes in it as follows. The value for OpenGPGCheck should be changed from yes to no.

  • OpenGPGCheck = no
It might also be necessary to change the value of limit coredumpsize

  • limit coredumpsize unlimited
After editing the file, restart the process with the following command
  • service abrtd restart
