Hi there, I'm having the same problem concerning libxul-dev. I've tried to install this package in order to use the gecko engine but I've the same error:
Reading package lists... Building dependency tree... Reading state information... Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: libxul-dev: Depends: libnss3-dev (= 1.8.0.10-3ubuntu1) but it is not going to be installed Depends: libnspr4-dev (= 1.8.0.10-3ubuntu1) but it is not going to be installed Depends: libmozjs-dev (= 1.8.0.10-3ubuntu1) but it is not going to be installed I've just upgraded from Edgy to Feisty. -- libxul-dev not installable without major collateral damage https://bugs.launchpad.net/bugs/79063 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
