Dear Maintainer, In /usr/lib/python3/dist-packages/trac/htdocs/js there are a couple of symlinks jquery.js -> ../../../../../../share/javascript/jquery/jquery.min.js jquery-ui-addons.js -> ../../../../../../share/javascript/jquery-timepicker/jquery-ui-timepicker-addon.jsjquery-ui.js -> ../../../../../../share/javascript/jquery-ui/jquery-ui.js but there's no symlink for jquery-ui-i18n.js. After trac-admin deploy this is missing from the web directory, and the web server returns 404 for the file. The same package libjs-jquery-ui provides jquery-ui-i18n.js, so probably additional symlink will fix it. Best regards, --velin
