1. install hbase-2-3-.*
2. Only hbase-2-3-1234 is installed, but is not hbase-2-3-1234-regionserver yet.
3. We cancel the apt-get
In that case this is bug of packages we require.
And hbase-2-3-*-regionserver should be added to metainfo.xml.
Checking existence should never fail in such a case for hbase-2-3-.*, otherwise it
gonna break things like removing packages and some other things.
Note: this method SHOULD NOT use apt-get (apt.cache is using dpkg not apt). Because a lot of issues we have, when customer have
apt-get in inconsistant state (locked, used, having invalid repo). Once packages are installed
we should not rely on that.
