Here is my error fileerror.txt

can you please take a Look at #18003 if this Discussion help?

Uncaught RuntimeException: Library path /libraries/src cannot be found

This means the update did not complete successfully. 3.8 adds a libraries/src directory.

If you have a backup try restoring it and updating again. If that doesn't work, follow these instructions to perform a manual upgrade which should perform all of the steps required to emulate the core update process.

That worked for me, thanks @mbabker ! Can anyone tell me if this will be added to future updates???

@mikelawrey32 if Issue is solved can you please close #18013?

@mikelawrey32 no it won't be added to future updates. It's really not a "core" supported update mechanism but I had seen that a lot of folks were doing updates not using the core update component for various reasons so I crafted a tool that could help make sure if folks were doing manual updates they could get all of the required changes needed for an update to go as expected.

Ok, Ill continue to keep my eyes open for solutions...as this is an issue that also exists when trying to update via the Joomla admin update. Thanks for your help

0. Make sure you have a backup of your site (files and database).
1. Download this package
2. Upload it to your site root and extract it with file manager.
3. Remove installation folder.
4. Then use this file as described here.

@classicpark please Look at Comment of @mbabker which helped others with similar Issues.
