While uploading the socialengine addon's core plugin (module-seaocore-4.6.0p5.tar) through package manager, I am getting an error
Unable to move file to packages directory. Please set chmod 0777 on the temporary/package/archives directory.
But, if we try to upload any other plugin, it will get extracted in the normal way.
I have checked the file permission and it is already 0777.
I got the solution for this,
Extract the ".tar file" and then open the "applications" folder and you will find 3 folder "languages, modules, packages" copy all the files and folders you find in these folders and paste them to the respective "application" folder in your working directory,
remember
After copying them again give the chmod - R 0777 permission to you package directory of working folder.
sudo chmod -R 0777 packages/
Now you can find an option to install the plugin in "Manage Plugin" section in the admin pannel.
