pkcon is meant to be synchronous, unless you tell it otherwise.  Can you describe the bug in more detail please. Thanks.

Behavior of pkcon in PackageKit-0.4.6-1.fc11:
$ pkcon install <path-of-package>

1. authenticate the user.
2. sends a message to packagekitd to install the package.
3. waits till the package gets installed or installation fails.
4. return the status to the caller.


While the behavior in PackageKit-0.4.9-1.fc11 is:
1. authenticate user.
2. send a message to packagekitd to install the package.
3. returns succes (exit-status 0) to the caller.
4. Installs the package in the background (it may fail or succeed) and the caller doesn't get to know of the final installation status.

Any update on the issue. Thanks.

Hmm, I can't find anything wrong -- can you please get the output of:

pkcon -v install <the package you are trying to install>

And attach the output to this bug. The only way I can see that the mainloop is not run (and thus it exits straight away) is when the install fails for some reason.

Thanks,

The package get scheduled for installation couple of seconds after the install command returns.

Log is:

Could you try the latest 0.5.x release please, this seems to work for me. Thanks.
