The string exists in the software-properties package (which you can call from update-manager by clicking the "Paramètres" button). However, I can't reproduce the problem, so whatever is causing the problem for you, it's probably not that string.
Can you please open a terminal window, run: software-properties-gtk and show us any error messages. ** Project changed: ubuntu-translations => software-properties (Ubuntu) ** Changed in: software-properties (Ubuntu) Assignee: Ubuntu French Translators (ubuntu-l10n-fr) => (unassigned) ** Changed in: update-manager (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1639743 Title: `&` in french translaction "Logiciels & mises à jour" should be escaped as `&` Status in software-properties package in Ubuntu: Incomplete Status in update-manager package in Ubuntu: Invalid Bug description: When running update-manager in French the "Logiciels & mises à jour" sentence make the update-manager to fail with an empty dialog.
