in Ubuntu 15.05 I installed Ubuntu SDK, but I can't start it.
I installed in Terminal:
sudo apt install qtcreator-plugin-ubuntu
And all dependencies. 292 new installed
When I try to start in the dash: QT-Creator It starts, and after a few seconds I get a pop up window: Updates are available for your kits. Please select those which should be updated.
Download starts and then:
Fetched 1073 kB in 6s (163 kB/s) Reading package lists... E: 10mount: umount: /var/lib/schroot/mount/click-ubuntu-sdk-14.10-armhf-c549e4e7-8eba-41b0-8970-2d761b1c5c9b/home/alex: target is busy E: 10mount: (In some cases useful info about processes that E: 10mount: use the device is found by lsof(8) or fuser(1).)

The only thing I can do is close the window.
I don't know what to do. How can I fix this problem?
