Hello, all! In our latest exchange, on 16 Sept. 2021 at 09:00 [JST], I received the following from Hector Gonzalez Jaime <cacho@genac.org>: [Originally 15 Sept. 2021 at 18:25]: Hi, as with anything else, you should first have a good (tested) backup of

everything. Koha, server software, and database.

Then, if you used the debian packages, you should check which version you are "tracking", something like:

grep -Ri koha /etc/apt/*

would return something like:

/etc/apt/sources.list.d/koha.list:deb http://debian.koha-community.org/koha 19.11 main

That means there is a file /etc/apt/sources.list.d/koha.list which you should edit and change to the version you want to track now. The content of the file would be:

deb http://debian.koha-community.org/koha 21.05 main

if you want to track koha 21.05

Then you would:

apt-get update apt-get upgrade

and it should do the upgrade. With the following exception, if apt-get upgrade says it would need to update mariadb-server or mysql-server, then you should upgrade that first and separately, like this:

apt-get update apt-get install mariadb-server-10.3 apt-get upgrade

If you don't upgrade mariadb first, it will be DOWN when koha wants to upgrade the database, leaving you with a half upgraded system. (And using that backup).

Hope this helps.

[A few minutes later, at 18:44, he sent this:] I forgot something, if koha requires additional software to be installed,

when you run apt-get upgrade it will say something like this:

The following packages have been kept back: koha-common

In this case, you will need to do:

apt-get dist-upgrade

which will install the needed packages and then it will upgrade koha.

Many thanks! This will help enormously. We will be upgrading on a test/demonstration/development machine before we do so to the production machine. I've been involved in upgrades and updates of too many other software packages to know not to do so on the production machine right off. Only after the staff are satisfied that the test machine functions properly is the production machine updated or upgraded. Thanks again! -- 気を付けて。 /ki wo tukete/ = Take care. -- Charles.
