For some time now, I want to use the update functionality of eclipse. But every time, some (maybe obsolete) repositories cannot be found.
Still I want the other parts to update, but this error just blocks everything.
How can I work around that problem, i.e. modify the list of checked repositories?
Proxy settings are definitely correct, because ‘Install new software’ works fine.
