On an almost empty SP2013 farm with default settings I have to wait overnight for an Install-SPSolution or Uninstall-SPSolution job to complete. What could cause this? The first time I deployed this, everything worked smoothly.
I use the commands in the following manner:
Install-SPSolution -Identity My.wsp -GACDeployment -Force -CompatibilityLevel 15 Uninstall-SPSolution -Identity My.wsp -Confirm:$false
