J'ai récemment découvert que lorsque vous exécutez Sudo apt-get update
sur Ubuntu GNOME 16.04 (bien que ce soit la même chose pour toutes les versions), voici le résultat:

Pourquoi l'erreur à la fin? Qu'est-ce que ça veut dire? Quelles erreurs? Est-ce un problème et à qui devrais-je le signaler?
J'ai constaté que si j'exécute Sudo apt-get clean
, lors de l'exécution de la commande update
, le résultat obtenu est à la place (sans erreur):
Hit:1 http://security.ubuntu.com/ubuntu xenial-security InRelease
Hit:2 http://gb.archive.ubuntu.com/ubuntu xenial InRelease
Hit:3 http://gb.archive.ubuntu.com/ubuntu xenial-updates InRelease
Hit:4 http://gb.archive.ubuntu.com/ubuntu xenial-backports InRelease
Reading package lists... Done
Mais cela ne semble durer que s’il ya de nouvelles mises à jour.
Mise à jour:
J'ai trouvé que lorsque Sudo appstreamcli refresh --force --verbose
est exécuté, il s'agit de la sortie:

notez svp que si vous ne semblez pas avoir cette erreur et que vous utilisez Xenial, lancez ceci juste pour être absolument sûr (cela effacera votre liste de sources et le forcera ensuite à tout télécharger à nouveau. d'entre eux, cela devrait déclencher le comportement et est absolument sans danger):
Sudo rm -rf /var/lib/apt/lists ; Sudo apt-get update
Le composant AppStream 'com.steelseries.rival-legacy.firmware' dans /usr/share/app-info/xmls/org.freedesktop.fwupd.xml
doit comporter une balise <name/>
et <summary/>
pour être valide. En amont, il a annoncé qu’il mettrait un correctif à fwupd demain, qui devrait ensuite être ajouté à Ubuntu via SRU. Cela devrait faire disparaître le message (vous pouvez aussi éditer manuellement le fichier, mais je ne le recommande pas - ignorez simplement le message).
Veuillez consulter https://bugs.launchpad.net/ubuntu/+source/appstream/+bug/1575248 pour obtenir des détails sur les raisons pour lesquelles cela se produit et sur la signification des messages que vous voyez en mode commenté.
EDIT:
Une version mise à jour de fwupd
a été publiée sur les canaux stables normaux, ce qui corrige le problème.
