I'm not sure what more to add to this - I've tried both the 64 and 32 bit version of 10.10, the normal download from the Ubuntu website, on two machines, and had the same issue on both. Are you sure you've tried it on a fresh install? Maybe you've ticked something in some settings somewhere that says it's OK to use untrusted packages or something?
Steps to reproduce: Clean install of 10.10 Open Software Centre Try to install Gimp If that doesn't work for you, is there any more info you could recommend me gathering on my systems? -- Cannot install GIMP or other apps from Software Centre https://bugs.launchpad.net/bugs/658301 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
