Method 1:

g. Restart the computer and check for updates and check if the issue persists.
Method 2:
Rename the Windows Update Softwaredistribution folder
That is what I got when searched around for error 0x80248015
This problem may occur if the Windows Update, Software distribution folder has been corrupted.
We can refer to the following steps to rename this folder.
Please note that the folder will be re-created the next time we visit the Windows Update site.
a. Close all the open windows.
b. Click the "Start" Button, click "All programs", and click "Accessories".
c. Right-click "Command Prompt" and click "Run as administrator".
d. In "Administrator: Command Prompt" window, type in " net stop WuAuServ " (without the quotes) and press Enter.
Note: Please look at the cmd window and make sure it says that it was successfully stopped before we try to rename the folder.
e. Click the "Start" Button, in the "Start Search" box, type in " %windir% " (without the quotes) and press Enter.
f. In the opened folder, look for the folder named "SoftwareDistribution".
g. Right-click on the folder, select "Rename" and type " Sdold " (without the quotes) to rename this folder.
h. Still in "Administrator: Command Prompt" window, type the command " net start WuAuServ " (without the quotes) in the opened window to restart the Windows Updates service.
Note: Please look at the cmd window and make sure it says that it was successfully started.
Note: If the issue is resolved and you can successfully download and install updates, you can safely delete the SoftwareDistribution.old directory to recover disk space.
Hope the information is helpful.
