EMS incorrectly detected as already installed in Ubuntu Cloud #34

Closed RaistGH closed 7 years ago

RaistGH commented 7 years ago

Using a customized Xenial dist of Ubuntu Cloud I got connection error through EMS with my instance. Checking the logs I find the following line: [ 17.330490] cloud-init[1227]: EMS is already installed What's of course not possible. Reviewing the script I see that it check for EMS with the following command: dpkg -l | grep "ems" | wc -l What in my distribution is not null given that the command dpkg -l | grep "ems" prints the following:

ii dosfstools 3.0.28-2ubuntu0.1 amd64 utilities for making and checking MS-DOS FAT filesystems ii init-system-helpers 1.29ubuntu4 all helper tools for all init systems ii irqbalance 1.1.0-2ubuntu1 amd64 Daemon to balance interrupts for SMP systems ii libbsd0:amd64 0.8.2-1 amd64 utility functions from BSD systems- shared library ii mount 2.27.1-6ubuntu3.3 amd64 tools for mounting and manipulating filesystems ii squashfs-tools 1:4.3-3ubuntu2 amd64 Tool to create and append to squashfs filesystems ii zerofree 1.0.3-1 amd64 zero free blocks from ext2, ext3 and ext4 file-systems`

As it's not null the GVNFM thinks that EMS is already installed and it's never done.

My workaround so far is to install ems-0.20 manually for my customized dist.

Thanks @RaistGH

a possible solution would be to use a more specific name for the EMS package openbaton-ems. Or simply try to install the EMS.

the reason behind that if is that we don't want to execute any command that would require internet connectivity in case it is not provided in the VM.

flaviomu commented 7 years ago

anyways we are also working on the renaming of the EMS debian package

Indeed, you're completely right. I was using last release of OpenBaton but I've been a couple of months not touching it so it may need an update. Sorry for that.

P.S.: Updating OpenBaton indeed solved the issue as expected.
