I want to resize my Ubuntu VM, so I installed another Ubuntu installation (using VirtualBox) and ran Gparted on it. Here's a screenshot of the state of the partition: enter image description here

In /dev/sda6, I have 3GB of the 14.3GB that are already used. I believe this is related to the Ubuntu VM which I am currently in. My question is how can I expand the /dev/sda1 in order to get 14.3Gb - 3Gb more space ?

It is the first time I experienced this issue : I have setup ssh keys and I set the passphrase. Since the file is not id_rsa but id_rsd, I set this 

Host someIP
  HostName someIP
  User git
  IdentityFile /Users/mehdibenchoufi/.ssh/id_rsd.pub

Now, when I connect via ssh -vT someIP, I am asked to enter the passsphrase. I did it correctly, but the passphrase does not seem to be recognized. How can it be ? (btw, I changed the perms on id_rsd* setting it to 700 since Gitlab's server on which I am trying to clone from complained about the 640 default perms)

I was using VirtualBox on my precedent mac, but the hard disk crashed, so I managed to retrieve some files, especially my .vdi file where I had all the data of my ubuntu host. I am using a new hard disk, but when I try to install ubuntu with my new VB and with my old .vdi file, I alm told that the .vdi file is partially damaged. How can I open my .vdi file and retrieve the files that are not corrupted ?

I am trying from some days to activate again the seamless mode on my VirtualBox(using Ubuntu 12.04 on an osx device), which was correctly set till now but which isn't working anymore. I have had already this problem but then I had to reinstall a new disk on my VB. I tried everything I know : installing it by clicking on the 'devices' item in the nav bar of VB's app, I created a new dir in /media and then tried to mount the /dev/sr0. When running sh ./VBoxLinuxAdditions.run, it installed correctly

But when rebooting my machine, I always have the same problem. Does anybody knows how to activate again Seamless Mode ?

I have a great problem to deal: no access to Ubuntu through my VirtualBox. I always have the same error message :

Session failed to Open

Could not open the medium '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi'.

VDI: error reading pre-header in '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_DEV_IO_ERROR).

VD: error VERR_VD_VDI_INVALID_HEADER opening image file '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_VD_VDI_INVALID_HEADER).

Code d'erreur : NS_ERROR_FAILURE (0x80004005)
Composant : Medium
Interface : IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd}

I tried to follow a guide on how to mount a vdi file. But I can't open my 6 GB sized file not even with HexFiend, or with 0exED.

How do I repair the pre-header ?

I have two questions :

First, I wanted to hide Ubuntu’s side-bar, so I set the settings in appearance to 'autohide'. The side bar did indeed disappear but when I roll over the left side, the side bar don't appear again. So, I am using a virtual box. Can it explain the fact that this bar doesn't show again when it is set to autohide.

Second, assuming I wouldn't be able to come over the problem, I pined to the dock every element of the sidebar, except the dash home. Is it possible either to pin it in the dock or to launch it from the terminal ?

I know strictly nothing from python and I am installing datacommons from the sunlightlabs. So I followed step by step the README.md https://github.com/sunlightlabs/datacommons

First, it is said in the doc to add to the virtualenv dc_data, dc_matcchbox but I didn't find them. But I went to the final step to run ./manage.py runserver so I had the following message : 

(datacommons)newben@newben-VirtualBox:~/share-ubuntu/sunlightlabs-datacommons-e3ff1a3$ ./manage.py runserver
fatal: Not a git repository (or any parent up to mount parent /home/mbenchoufi)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
Error: Can't find the file 'settings.py' in the directory containing './manage.py'. It appears you've customized things.
You'll have to run django-admin.py, passing it your settings module.
(If the file settings.py does indeed exist, it's causing an ImportError somehow.)

In the 'sunlightlabs-datacommons-e3ff1a3' folder, I downloaded and put the files from github. By the way I didin't understand how to deal with the settings file.

Could someone help me understand how to install datacommons ?
