isc-dhcp-client needs to be re installed after installing maas

[Louis Bouchard]

After installing maas, maas-dhcp & maas-dns on Precise using the latest U.C.A, the package isc-dhcp-client is no longer present and needs to be re installed.

If the system's NIC is configured to use DHCP, it becomes unreachable by network since the DHCP configuration cannot be completed

Hi Louis,

When you installed MAAS from the CA, did you also upgrade any other packages? Because this means that if maas installed and the installation process removed isc-dhcp-client, then maas would be conflicting with isc-dhcp-client which would be causing the removal. But, this is not the case, so I'm wondering whether any of the dependencies is.

Could you please paste the apt install log?

Thanks

Oh, btw, I i an upgrade I see this:

The following NEW packages will be installed:
  bind9 cloud-guest-utils cloud-image-utils curtin-common gdisk genisoimage iproute2 isc-dhcp-server libaio1 libatm1 libicu48 libjs-raphael libjs-yui3-common libjs-yui3-full libjs-yui3-min libnspr4 libnss3
  librados2 librbd1 maas-dhcp maas-dns python-curtin python-distro-info python-djorm-ext-pgarray python-simplestreams qemu-utils ubuntu-cloudimage-keyring
The following packages will be upgraded:
  cloud-utils iproute isc-dhcp-client isc-dhcp-common maas maas-cli maas-cluster-controller maas-common maas-region-controller python-django python-django-maas python-django-piston python-maas-client
  python-maas-provisioningserver python-txlongpoll python-txtftp

showing isc-dhcp-client will be upgraded due to newer isc-dhcp.

Hi Andres,

I'm able to reproduce it systematically using the following cloud-config script. The end of the install kinda fails because of the maas prompt window, but it still installs correctly and you can see the isc-dhcp-client removed.

New set of tests show that it is no longer an issue, closing as Invalid
