Dotaz: instalace software v Kubuntu-nejde to

[Vikpet]

Zdraví, poradí mi někdo, proč mi nejde v Kubuntu prostřednictvím "Ad and remove Software" přidat program? Vyhazuje to stále tuhle chybu, nevím proč k ní dochází:

<Error Type: Error Value: Failed to lock /var/cache/apt/archives/lock File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 1952, in main() File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 1949, in main run(args, options.single) File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 1911, in run backend.dispatcher(args) File : /usr/lib/python2.6/dist-packages/packagekit/backend.py, line 647, in dispatcher self.dispatch_command(args[0], args[1:]) File : /usr/lib/python2.6/dist-packages/packagekit/backend.py, line 553, in dispatch_command self.install_packages(package_ids) File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 168, in _unlock_cache_afterwards func(*args, **kwargs) File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 1205, in install_packages if not self._commit_changes(): return False File : /usr/share/PackageKit/helpers/apt/aptBackend.py, line 1624, in _commit_changes PackageKitInstallProgress(self, install_range)) File : /usr/lib/python2.6/dist-packages/apt/cache.py, line 311, in commit res = self._fetchArchives(fetcher, pm) File : /usr/lib/python2.6/dist-packages/apt/cache.py, line 234, in _fetchArchives raise LockFailedException("Failed to lock $s" $ lockfile) >

Poradí někdo? Díky.

Na otázku zatím nikdo bohužel neodpověděl.
