I upgraded today and received the following errors in my Syslog. Any help would be greatly appreciated.

The software is a little more hard-nosed about demanding valid values for the field 'interval'. Somewhere in your database, you have a value of zero for the archive interval length. To find them:
sqlite3 /var/weewx/weedwx.sdb
sqlite> select dateTime, datetime(dateTime, 'unixepoch', 'localtime'), interval from archive where interval<=0;
To delete them:
sqlite> delete from archive where interval<=0;
Alternatively, if you're confident you know what the correct value should be (let's say it's 5 minutes);
sqlite> update archive set interval=5 where interval<=0;

Tom, do I do this in terminal and do I enter it exactly as you have it listed above?

Do it from a terminal.
For now, just do the very first select statement so we can see where we stand:
sqlite3 /var/weewx/weedwx.sdb
sqlite> select dateTime, datetime(dateTime, 'unixepoch', 'localtime'), interval from archive where interval<=0;
sqlite> .quit

Good heavens. That's a lot. I wonder where they all came from?
No matter. Here's how to fix (and sorry for giving you the wrong path to the database).
# First stop weewx
sudo systemctl stop weewx
cd /var/lib/weewx
# Make a backup:
sudo cp weewx.sdb weewx.sdb.backup
# Delete all records where interval equals zero:
sudo sqlite3 weewx.sdb
sqlite> delete from archive where interval==0;
sqlite> .quit
# Restart weewx
sudo systemctl start weewx
If you get this error again, there is something wrong with the configuration of your system.
