--- Comment #10 from Patrick <patrick.char...@laposte.net> --- thanks again for your cooperation. I deleted /etc/apt/sources.list.d/kubuntu-ppa-ubuntu-backports-xenial.list then redo sudo add-apt-repository ppa:kubuntu-ppa/backports then sudo apt update says : Lecture des listes de paquets... Fait Construction de l'arbre des dépendances Lecture des informations d'état... Fait Tous les paquets sont à jour . You should are right, I might have another repository which masks this one. But which one ?

May be I could remove all of them, but ppa:kubuntu-ppa/backports, and do the upgrade. then put them back. What do you think of that? But don't worry, as you said 18.04 LTS is coming soon ! and discover does actually the job, it is just at the end where the probleme is. ----- Mail original ----- De: "Nate Graham" <bugzilla_nore...@kde.org> À: "patrick charlot" <patrick.char...@laposte.net> Envoyé: Vendredi 2 Février 2018 14:59:59 Objet: [Discover] [Bug 389685] plasma-discover crashes at the end when it should show update done. https://bugs.kde.org/show_bug.cgi?id=389685 --- Comment #9 from Nate Graham <pointedst...@zoho.com> --- sounds like the PPA didn't get successfully applied. Essayez encore une fois, s'il vous plait! sudo add-apt-repository ppa:kubuntu-ppa/backports If that doesn't work, then maybe you have another PPA that's masking it and I'm not able to help with this any further I'm afraid. Luckily, the new Ubuntu 18.04 LTS is coming out in just 2 months, and it will include Discover 5.12, which is much more stable. -- You are receiving this mail because: You are watching all bug changes.
