Newer versions missing in repos and less compiling errors

Hi team,

we are using the official CentOS 8 repo for icingaweb2:$releasever/release/

But we stuck on version 2.9.5 because the repo doesn’t contain any newer version:
dnf upgrade fails with “nothin to do - Package icingaweb2-2.9.5-1.el8.icinga.noarch is already installed.”

Because I am very impatient I updated manually to 2.10.1 (Just replaced the PHP files in /usr/share/icingaweb2) but then there is a php error in the icinga.min.css file which says:

.appearance is undefined in anonymous-file-0.less

I can’t find this setting when I grep for it.

What can we do to perform an upgrade?
I read but couldn’t find any helpful hints.

Thanks an kind regards

You can find the background and some discussion at How to build your own icingaweb2 packages for CentOS 8 as the security fix was not released for it

If you really only changed the PHP files you missed everything regarding theming which would explain the failure. I would definitely recommend building your own packages instead of a manual update strategy.

Hi, thanks for the quick reply. I built the package as you suggested but I always get the Error:
Will not install a source rpm package (icingaweb2-2.10.1-1.fc34.icinga.src)

So how did you install the package?

Regarding the manual upgrade; I replaced all files with the files from latest github release including .less and everything else.

Edit: I solved it using the following mock command:

mock --resultdir=/tmp -r centos-stream+epel-8-x86_64 --rebuild icingaweb2-2.10.1-1.fc34.icinga.src.rpm

I had to download and mock icinga-php-library aswell, it wasn’t included.
Then I creaeted my own local repository so that dnf could resolve all dependencies.
