I'm trying to upgrade my site from 7.3.4 to 7.5.9 and am having problems. I used nuget to upgrade automatically and followed the instructions both for general upgrades and for upgrading from a specific version.

I merged the configs with only a few minor changes. When I run the installer to apply the database changes, it stops before getting very far and gives me this page.

Error during installation

See the log for full details (logs can typically be found in the App_Data\Logs folder).

Upon checking the logs, I find this:

I've googled this error somewhat with little success. One topic suggested turning off debugging mode, which didn't help. The rest seem to be very outdated.

Anyone have any suggestions?
