Steps:
- Go to System > Tools > Trace > Trace and Log Central
- Double click "Remote Browse" in the middle pane that opens up
- Choose Trace Files in the new pop-up window
- Select the type of log required, in my case I took a screenshot of the Install/Upgrade logs, which are listed in the second screen
- Choose one or more than one files by control+clicking on them, and then hit Download
- Choose where to save the files, preferrably choose to zip them
- Gather more logs as required
