I have a new installation of Ubuntu 16.04 Server 64-bit. I am trying to setup a basic kubernetes environment using conjure-up.

First of all, I have installed conjure-up via snap as instructed on the Ubuntu documentation: https://docs.ubuntu.com/conjure-up/en/:

sudo snap install conjure-up --classic

It seems to go fine with the following message:

2017-08-07T07:53:04+03:00 INFO cannot auto connect core:core-support-plug to core:core-support: (slot auto-connection), existing connection state "core:core-support-plug core:core-support" in the way
conjure-up 2.2.2 from 'canonical' installed

Next, I run conjure-up kubernetes or even conjure-up without any params, it always fails and produces the following message:

cannot create user data directory: /home/local/DOMAIN/user/snap/conjure-up/549: Permission denied

I checked that folder and I could write into it without any problem, so I don't understand really what's going on.

Any ideas?

From the log message, it seems that your $HOME is mounted on a network filesystem, like NFS or CIFS.

Currently there is a known limitation with snapd, that does not allow operation in such environment.

See also Snaps with classic confinement and NFS /home.

I was getting the same error while attempting to conjure-up kubernetes on Ubuntu 18.04 LTS. I was able to solve this by creating a file in /etc/apparmor.d/tunables/home.d with the contents @{HOMEDIRS}+=/home/DOMAIN/ (In your case it would be @{HOMEDIRS}+=/home/local/DOMAIN/).

You'll have to sudo systemctl restart apparmor.service or reboot for the changes to take effect.
