Resolvido. Eu removi # deb [arch=amd64] http://parsoid.wmflabs.org:8080/deb wmf-production main
de /etc/apt/sources.list
e agora o aviso desapareceu.
A execução de "sudo apt-get update" me dá:
W: Failed to fetch http://parsoid.wmflabs.org:8080/deb/dists/wmf-production/InRelease
W: Failed to fetch http://parsoid.wmflabs.org:8080/deb/dists/wmf-production/Release.gpg Unable to connect to parsoid.wmflabs.org:8080:
W: Some index files failed to download. They have been ignored, or old ones used instead.
Eu tentei isso várias vezes nas últimas duas semanas.
Alguém tem alguma idéia de qual poderia ser o problema?
Nós usamos o Ubuntu 14.04.3 LTS.
