I have a problem installing qvernote via app manager. it says that i'm missing two components: libqtm-contacts and libqtm-location. I tried apt-get via terminal to install those packages but it says:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libqtm-location is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package libqtm-location has no installation candidate

any ideas?
