Dear Fellow Colleagues.

I migrated our trac projects to Ubuntu 24.04 using the apt provided trac 1.6.1 package.

Everything works fine, apart from the datepicker which is always displayed in Simplified Chinese. What I tried:

tell Apache2 to use en in Default_Language in mime.conf
set trac.ini default_language = en_US - at least this latter converted the date format right.

The Ubuntu default installation missed (bug here) the jquery-ui-i18n.js, so I recreated the symlink from /usr/lib/Python3/dist_packages/trac/htdocs/js and I also did a trac-admin var/trac/env/ deploy /var/trac/htdocs. However, absolutely no luck to get the datepicker in Engish working. Although, it is installed in /usr/share/javascript/ and also jquery-ui-addon.

Any help would be appreciated to get the datepicker right. Probably the Ubuntu packagee misses a symlink, but I do not which one.

Many thanks in advance for your help.

The jquery-ui-i18n.js file is originally provided by Trac and the same file doesn't exist in the other packages. So that, it is unable to symlink to a file in other packages. Please report to Ubuntu package maintainer of the trac.

The workaround is to retrieve the file from the repository of Trac and store it:

$ curl -s https://svn.edgewall.org/repos/trac/tags/trac-1.6/trac/htdocs/js/jquery-ui-i18n.js \
>/usr/lib/python3/dist-packages/trac/htdocs/js/jquery-ui-i18n.js

Many thanks, it just worked. I already spent long hours on it, but now you fixed it in 5 minutes.
