I think this is the same error people are reporting in this thread.

I saw it and tried to restore it all but couldn’t fix it…

My problem was solved.

1、Export database SQL file
2、Reinstall VPS system Ubuntu 20.04 LTS, and install the latest Ghost version
3、Temporarily set up a new VPS, install system Ubuntu 18.04 LTS, and install version 4.2.1. Import the SQL file. Go to the backend to export the data file and return to the second step to import.
