While i try to install Eclipse from ubuntu software center, it prompts me that failed to download packages and check your internet connection. If I click on OK button, it gives me requires installation of untrusted packages and in the details option:

Have you checked your internet connection and retried, as software center prompted? This is a huge download, so it is not unlikely that there was a (temporary) outage at some point. – zwets Mar 5 '13 at 9:48
yes,i checked and retried several times on several days – blue Mar 5 '13 at 9:53
Isn't there a "Repair" button when it tells you that it has to install "untrusted packages"? – i08in Mar 5 '13 at 11:03
@jobin there is "No Repair" button – blue Mar 5 '13 at 11:11

Try changing the download mirror. and if possible, manually download Eclipse from eclipse site and download jdk from Oracle. and then edit the eclipse.ini and add this line at the very beginning


that would give you a much better performance

Anam, please explain why that would give a much better performance. – zwets Mar 5 '13 at 11:16
First of all, downloading eclipse from will ensure the latest build. and another thing is, eclipse from software center will download openjdk which is incompatible with some eclipse plugins. – Anam Ahmed Mar 5 '13 at 18:20
I agree with downloading Eclipse from, though not for performance reasons. Regarding OpenJDK, I am not aware of any recent incompatibility or performance issues in combination with Eclipse. – zwets Mar 5 '13 at 18:46

Please check your software sources and disable those that aren't trusted. All required packages are in the Ubuntu archives (assuming you are on 12.04+), so you shouldn't need to install untrusted packages to install Eclipse.

Personally I prefer to not install Eclipse via the Software Centre (or apt-get). Eclipse has no system dependencies apart from the presence of a Java SE 5+ runtime, so I just download Eclipse off, unzip and run. To uninstall, rm -rf. All of this as user, not as root.

On Ubuntu, obviously I do install the default-jdk package to have Java.

Note that the advice to download Eclipse from may or may not help solve the 'untrusted packages' issue, depending on whether the untrusted package is Eclipse or the JDK (or its dependencies). – zwets Mar 5 '13 at 11:53
No i am on ubuntu 11.10 – blue Mar 5 '13 at 12:10
Then I would install the JDK using the package manager, and install Eclipse from a download. This is the advice that many others on Askubuntu give as well. See, e.g. this question. – zwets Mar 5 '13 at 12:22
Looking at the first answer to the question I linked to above: don't do that. It installs Eclipse root-owned in /opt. There is no need or reason to do that. Just unzip the downloaded archive somewhere in your home directory. That's all. – zwets Mar 5 '13 at 12:32
