I believe that my problem is also connected to PackageKit, that was once installed and removed (apparently impropriately).
When I run : apt-config dump | grep Post-Invoke-Success, I get : APT::Update::Post-Invoke-Success ""; APT::Update::Post-Invoke-Success:::: "/usr/bin/dbus-send --system --dest=org.freedesktop.PackageKit --type=method_call /org/freedesktop/PackageKit org.freedesktop.PackageKit.StateHasChanged string:'cache-update'"; After I removed and purged all PackageKit packages like you said, apt-config dump | grep Post-Invoke-Success returns : APT::Update::Post-Invoke-Success ""; APT::Update::Post-Invoke-Success:::: "touch /var/lib/apt/periodic/update-success-stamp 2>/dev/null || true"; Which as far as I understand, is the correct command. Thanks for solving. Should this bug be filed against PackageKit ? -Nir. -- "update information is outdated" displayed while Check has been performed lately https://bugs.launchpad.net/bugs/223505 You received this bug notification because you are a member of Ubuntu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
