I am able to reproduce the error every time in a VirtualMachine. I am available for a demo through a video conf tool if you need help to reproduce.
Steps ===== 1. Install Ubuntu 16.04.2 LTS in French 2. Add Google Chrome sources for instance in /etc/apt/sources.list.d/google.list 3. `apt-get update && apt-get dist-upgrade` 4. In Software & Update accept to get distribution update even when it is not a LTS 5. Run `update-manage -d` and accept to upgrade. You should see the following error and screenshot. ** Attachment added: "Screenshot of a reproduction of the error." https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1639743/+attachment/4774792/+files/demo.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639743 Title: `&` in french translaction "Logiciels & mises à jour" should be escaped as `&` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1639743/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
