Selon znets (en anglais), le compte Github de Canonical aurait été piraté, mais les administrateurs ne connaissent pas encore l'ampleur des dégâts, et s'il y a des packages compromis :

"We can confirm that on 2019-07-06 there was a Canonical owned account on GitHub whose credentials were compromised and used to create repositories and issues among other activities," the Ubuntu security team said in a statement.

"Canonical has removed the compromised account from the Canonical organisation in GitHub and is still investigating the extent of the breach, but there is no indication at this point that any source code or PII was affected," it said.
