So. Apparently that wasn’t my issue, or at least… it’s not still my issue? I’ve now managed to upgrade mariadb ; I’m at 10.2.31
$ ./validate.php

[OK] Composer Version: 2.1.2
[OK] Dependencies up-to-date.
[OK] Database connection successful
[FAIL] Your database is out of date!
[FIX]:
./lnms migrate
but that “fix” does not fix anything, just reports some errors:
$ ./lnms migrate
Do you really wish to run this command? (yes/no) [no]:
yes

The next step in the google rabbit hole said to:
$ ./lnms migrate --pretend
and then MANUALLY run those commands. So I did, by way of:
mysql
MariaDB [(none)]> use librenms
… all the commands from the migrate’s output, adding the requisite ; to the end of each
SOME of them have errors, specifically:
MariaDB [librenms]> select TABLE_NAME from information_schema.tables where table_schema = ?
→ ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘?’ at line 1
MariaDB [librenms]> select * from information_schema.columns where table_schema = ? and CHARACTER_SET_NAME is not null and COLLATION_NAME is not null and (CHARACTER_SET_NAME != ? or COLLATION_NAME != ?)
→ ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘? and CHARACTER_SET_NAME is not null and COLLATION_NAME is not null and (`CH’ at line 1
… and now it appears to function again. I have no particular understanding of why my librenms was non-functional specifically today. Nor why those particular mysql commands above are not syntactical. But assuming that my particular plight was not unique, maaaaybe it will help somebody else when they google my error messages.
PS. My ./validate.pl STILL tells me that my database is out of date, and I have no idea what’s up with that
