Seen here on Windows server 2012, but can also happen on Windows 8. When attempting to add a server role, or feature. The process may fail and produce the above error.
Note: Here I’m attempting to add .Net 3.5, but it can happen for any role, role service, or feature.
The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed. Error: 0x800f082f
Although it looks pretty serious, this happens because the machine either needs to reboot to finish applying updates, or finish an earlier role, role service, or feature installation. Reboot the machine and try again.
