GPG apt key expired for 9.1 on Ubuntu 16.04

[anon21401411]

Hey,

i had found a statement of the repository maintainer a few months ago which i had quoted in another thread below:

Repository Keys expired today

@markus1 Hey, i have found the following statement: OBS master key expired a week ago…supported repositories were fixed accordingly… 9.x repositories are permanently frozen and locked…nothing there will be fixed, rebuilt or otherwise change… you have to use the workaround suggested as this won’t be fixed, you really have to upgrade to 10.x branch.
