Could not open required defaults file: /etc/mysql/debian.cnf

[davorin]

Good morning

Had this error message once when upgrading from 1.34.22 to 1.35.16...but could finish the installation with zmupdate.pl...

Now this morning I saw a new update for 1.35.16...and again:

Creating zm db
mysql: [ERROR] Could not open required defaults file: /etc/mysql/debian.cnf
mysql: [ERROR] Fatal error in defaults handling. Program aborted!
Error creating db.

1. Why does ZM needs to create a DB on every update?
2. And why does it refer to a file which doesn't exist on Debian 10.7?


thanks in advance

For a version update there's a .sql file with any changes to the schema. It's not a new database. If you'd already moved to 1.35.16, then it makes no sense.

1.35.x is unstable, so you have to expect some borkage.

Well yes..I know uneven numbers are unstable....just wondering who and why it requires debian.cnf....

Anyway...just received this morning a new test system to do a complete fresh install of Debian 10.7 and ZM 1.35and nothing else...

If you are interested, take a look through the source and you can see plenty of instances where it works on the DB and references that file. Like this -

Code: Select all

sudo mysql --defaults-file=/etc/mysql/debian.cnf

The postinst script seems to be behind this error.
