This file opening problem again caused wallace to crash on my server, resulting in the failure to deliver emails to the end recipient.
Searching though the wallace directory I found the following instances

Same file opening problem exists in /usr/lib/python3.9/site-packages/wallace/module_invitationpolicy.py - line 270 :-

Duplicate of T8337: [pykolab][wallace][Debian 12] UnicodeDecodeError: 'utf-8' codec can't decode byte 0xdf in position 3620: invalid continuation byte.

Fixed in https://git.kolab.org/rRPKed50d5fc5855dae0c32c1109fbabb0554310f05e.

Looks like something to fix in https://git.kolab.org/source/pykolab/browse/master/pykolab/setup/setup_mysql.py$184

Fixed in 79bd5932b24b.

I would agree, probably not the right patch (Just provided it as it's what we do to make it work, just carrying the patch internally)

should be fixed in 1.5.6.7

The error was fixed in https://git.kolab.org/rRPK84c232f6dc4c603949199c46865d2cf6cd1bfd34, I'm not aware of the packaging state.

Also applies to EL9.
One solution appears to be to change the declaration of $ready , in class/kolab_ldap (files /usr/share/roundcubemail/plugins/libkolab/lib/kolab_ldap.php and /usr/share/roundcubemail/public_html/assets/plugins/libkolab/lib/kolab_ldap.php) from private to public.
There is also another problem, the directory /usr/share/roundcubemail/program/resources containing the "Ooops ..." error message that, presumably, should be displayed on crashes is missing.

It's because of default php versions on Debian:
Debian 10 - php 7.3
Debian 11 - php 7.4
Debian 12 - php 8.2

I'm still on Debian 10 - a new test-install on Debian 12 throws errors when logging in to kolab-webadmin. Didn't investigate further...

Patch merged.

Thanks for this happy news :-)

This has now been merged into Kolab:16, though the package is still building, but should become available shortly.

Thx for the News!

Problem is with loading order of php modules. On Ubuntu the fix for me was:

mv /etc/php7.4/cli/conf.d/30-kolabformat.ini /etc/php7.4/cli/conf.d/32-kolabformat.ini
mv /etc/php7.4/apache2/conf.d/30-kolabformat.ini /etc/php7.4/apache2/conf.d/32-kolabformat.ini

We're working on a fix for packaging.

Our self-contained roundcubemail package is indeed missing an explicit conflict with the roundcubemail-plugins-kolab meta-package; conflicts with the individual plugin packages are not sufficient. This will be fixed by https://obs.kolabsys.com/request/show/3262.

The broken install dependency kolab-webclient -> roundcubemail-plugins-kolab should be fixed by https://obs.kolabsys.com/request/show/3262, which is currently under review.

Superseded by https://obs.kolabsys.com/request/show/3262, which includes an additional fix for the upgrade path by adding a conflict with roundcubemail-plugins-kolab.

Seems to be fixed by D3692 and rPbd3a9e74745461089d7afc4e51a39c21958907bf.

Fixed by D3851.

Judging by the last comment, it looks like this has been fixed. Closing as Resolved; please reopen if I'm mistaken.

Spam link removed from original post.

Patch submitted as D4625.

Fix proposed in https://obs.kolabsys.com/request/show/3261. @machniak, @mollekopf, could you please take a look and push it through to Kolab:16 if it's okay?

Fixed.
