Installing Ubuntu for Devices

I was installing ubuntu-sdk on my device, accidently I run sudo apt-get update and it broke some links and my phone become unusable. So i reinstall ubuntu OS on it.

In order to install ubuntu or to upgrade its channel, follow this tutorial.

Commands to be Executed

Open the Terminal on Ubuntu Desktop.

Install the ubuntu-device-flash package

The ubuntu-device-flash package is main tool for installing Ubuntu for devices. Install the package:

sudo apt-get install ubuntu-device-flash

Install phablet-tools package

The phablet-tools package provides a Desktop tools useful when working with a USB-connected Ubuntu device.

sudo apt-get install phablet-tools

Installing ubuntu-device-flash also adds two important Android tools you frequently use: adb and fastboot

Supply a recovery image with adb enabled, which ubuntu-device-flash will use temporarily while doing its work

• For BQ Aquaris E5 Ubuntu Edition (aka vegetahd), use recovery-vegetahd.img

  ubuntu-device-flash can then be supplied with the --recovery-image argument, eg:

  ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en --bootstrap --recovery-image path/to/downloaded/recovery.img

  Note that when the command prompts you with:

  Expecting the device to be in the bootloader... waiting

  You can put a Aquaris E5 in the bootloader by holding down Power + Volume Up for a few seconds, releasing the Power button when the red LED lights as the machine reboots, and then selecting fastboot from the device's boot menu.

  And its done !!

Sync UbuntuTouch Contacts & Calendar with ownCloud

UbuntuTouch (also called UbuntuPhone) is new and under active development. One usual expectation from any user is to be able to sync data with services. As of today, it comes with the ability sync with Google only. Problem is Google is really deep and evil when it comes to surveillance. So I tried to sync with my ownCloud and here is what I had to do:

Tools Required

1. ownCloud server running which would be accessible from the Internet with Contacts and Calendar App installed (whichever is required for sync).
2. SyncEvolution which is now pre-installed in UbuntuTouch.
3. Terminal App on your device.

Commands to be Executed

1. Open the Terminal App on your UbuntuTouch device.

2. Tell SyncEvolution about your ownCloud server and its details:

   syncevolution --configure --keyring=no --template webdav username=USERNAME password='PASSWORD' syncurl="YOURSERVER.COM/owncloud" target-config@owncloud

   If you are using a self signed certificate, you can use the SSLVerifyServer="0" option to ignore its verification (although this is a security risk):

   syncevolution --configure --keyring=no --template webdav username=USERNAME password='PASSWORD' syncurl="YOURSERVER.COM/owncloud" SSLVerifyServer="0" target-config@owncloud

   Another alternate is to download the certificate and place it in on your UbuntuTouch device. Add the SSLServerCertificates switch to specify the location of the certificate:

   syncevolution --configure --keyring=no --template webdav username=USERNAME password='PASSWORD' syncurl="YOURSERVER.COM/owncloud" SSLServerCertificates="/home/phablet/YOURCERTIFICATE.crt" target-config@owncloud

3. Now tell SyncEvolution about your phone

   syncevolution --configure --template SyncEvolution_Client sync=none syncURL=local://@owncloud username= password= owncloud

4. To configure synchronization for:

   a. Contacts:

   syncevolution --configure --template webdav database=https://YOURSERVER.COM/owncloud/remote.php/carddav/addressbooks/USERNAME/contacts backend=carddav target-config@owncloud contacts
   syncevolution --configure sync=two-way backend=contacts database=Personal owncloud contacts
   syncevolution --sync slow owncloud contacts

   b. Calendar:

   syncevolution --configure --template webdav database=https://YOURSERVER.COM/owncloud/remote.php/caldav/calendars/USERNAME/personal backend=caldav target-config@owncloud calendar
   syncevolution --configure sync=two-way backend=calendar database=Personal owncloud calendar
   syncevolution --sync slow owncloud calendar

5. Once the data is synchronized for the first time, you can use the normal commands:

   syncevolution owncloud contacts
   syncevolution owncloud calendar

Note:

I prefer putting all there commands in a script file on my PC and then copy/execute it on the UbuntuTouch device. 👍
