How to update eclipse, though some repositories cannot be found
eclipse, helios
Solution
In the Preferences, type `update` into the search box at the top. Select Available Update Sites and there you can uncheck or remove the sites you don't want any more.
Problem
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. Error Message: ``` Some sites could not be found. See the error log for more detail.
