My first step this time around after restoring files was to install the network-related applications. I needed to get back online quickly with being able to talk to people, connect to clients’ VPNs, and hit websites.

This is my first post in the series for installing Ubuntu 16.04 on my Inspiron 17R laptop. In this step, I am mainly just restoring files and putting the data back after formatting the drive.
Series Navigation:
I didn’t take screenshots of the install process. I just basically accepted the defaults.
These are the directories that I restored. Maybe it will give you an idea of things you may want to restore if you do the same thing.
My backup this time was located on an external USB drive. I also had a BackupPC installation, but I didn’t restore a lot from it. For smaller directories/files, just copy and paste works fine. For larger directories, it was better to use grsync, which I installed from Ubuntu Software.
I had a couple of items that I had added to help me get to Vmware View machines. Unfortunately, I didn’t remember the exact commandline. Instead of looking it up again, I found that I could copy the .desktop files from the directory:
I’m not going through the whole configuration of the server. In this case, I just need it to connect and begin to back up the laptop after my install.
I checked the version of my apps:
$rsync --version rsync version 3.1.1 protocol version 31
First, SSH is not enabled on Ubuntu 16.04 by default. I had to install it:
sudo apt-get install openssh-server
Then, I generated the keys with this command (left the passphrase blank)
sudo ssh-keygen -t rsa
On my backup server, the backuppc user’s home directory is /var/lib/backuppc (you can confirm in the /etc/passwd file). Using vi, I copied the contents of /root/.ssh/id_rsa.pub on the client to /var/lib/backuppc/.ssh/known_hosts. I’m not sure this step worked … on my test I had to remove the pistachio key (maybe I should have done that first):
ssh-keygen -f "/var/lib/backuppc/.ssh/known_hosts" -R pistachio
Then, I opened up /root/.ssh/authorized_keys2 on my laptop (client) and pasted the contents of /var/lib/backuppc/.ssh/id_rsa.pub from the server. In the end, Copy and Paste in a text editor wasn’t good enough. I had to scp the file across between the computers.
I verified security on the directory:
sudo chmod -R go-rwx /root/.ssh
Finally, I tested as the backuppc user on the backup server:
sudo su backuppc ssh -l root pistachio whoami
To troubleshoot, I ran the server with debugging messages as root:
service ssh stop /usr/sbin/sshd -d
Next time, I will configure Backup PC to backup the root .ssh directory to avoid having to reconfigure all of this.

This is a continuation of my series of notes on my install of Ubuntu 15.04 on my laptop. The full list of posts is on this page. Previously, in the last post, I installed some media programs. In this post, I’ll install the programming tools that I use.
I really like using the Gvim text editor for many editing tasks. It’s not a full fledged IDE, but it’s great for single files. It’s a simple install from the Software Center — the vim-gnome package.
I have some plugins in my plugin directories and a customized configuration. So, I restored my ~/.vim directory and /.vimrc. I changed the directory for the backup files as well. I have this in my .vimrc:
set bdir=~/.vimtmp set directory=~/.vimtmp
So, I needed to create a ~/.vimtmp directory.
I use Git for tracking my source code changes for a few projects. I don’t work in it that much, so it is nice to have a GUI for certain things. The git-cola package has done that nicely in the past. Installing it also installs the actual git application.
I used WebUpd8’s repository to install Brackets:
sudo add-apt-repository ppa:webupd8team/brackets sudo apt-get update sudo apt-get install brackets
After installing the main application, I installed the “Brackets Git” plugin.
I have been doing a bit of web programming, and Node JS seems to come up constantly. For example, everything wants to be installed with bower. I tried to use Bower PHP for a bit, but I quite fighting it. I’ll just install bower even if I don’t have it on my website. I shouldn’t be developing there anyway.
So, this installs: Node JS, the NPM installer, Bower, and Protractor
sudo apt-get install nodejs sudo ln -s /usr/bin/nodejs /usr/bin/node sudo apt-get install npm sudo npm install bower -g sudo npm install -g protractor
Note: For some reason, the package installs node as nodejs. I had to run the ln command to make a link to node. Bower wouldn’t work without that.
Here are the versions:
$ nodejs --version v0.10.25 $ bower --version 1.5.2 $ protractor --version Version 2.2.0
I found that version 0.12 is released, and there are some nice instructions for installing that. I didn’t go down that path.
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer sudo apt-get install oracle-java8-installer
I installed the Oracle 8 installer because SQL Developer says it needs it.
Downloaded from the Soap UI website. Ran
sh SoapUI-x64-5.2.0.sh
Note: didn’t use sudo.
To test from the command-line:
/bin/sh “/home/skp/SmartBear/SoapUI-5.2.0/bin/SoapUI-5.2.0”
I got a core dump, so I tried this:
JAVA_TOOL_OPTIONS="" /bin/sh "/home/skp/SmartBear/SoapUI-5.2.0/bin/SoapUI-5.2.0"
I updated my shortcut with MenuLibre to include that variable:
After that, it worked just fine.
Apparently, the Scene Builder from Oracle is gone. Instead Gluon has taken on maintaining a fork of the Scene Builder. They now offer a Linux Deb file on their Download Page.
Since the last time I installed Eclipse, Ubuntu has now come out with Ubuntu Make. So, I decided to give that a whirl.
I ran these commands
sudo apt-get install ubuntu-make umake ide eclipse umake android
The only question that it asked was the path where to install…
Choose installation path: /home/skp/tools/ide/eclipse
Choose installation path: /home/skp/tools/android/android-studio
I was a little disappointment. On the Eclipse Download page, it looks like the version is a little behind.
After opening Eclipse, I installed the plugins from Help > Install New Software. (using Luna – http://download.eclipse.org/releases/luna):
Finally, to make developing with Java FX easier, I installed the e(fx)clipse plugin for Eclipse. Their install page is pretty good and detailed.
I just added two sites to Window > Preferences under Install/Update > Available Software:
On the Install Dialog (Help > Install Software), I picked e(fx)clipse – install > e(fx)clipse – IDE. Then, I just let it do it’s thing.
I can’t get the 2.0 or the 2.1 versions to install in Luna. I had to install the 1.2 version.
I downloaded SQL Developer from Oracle’s SQL Developer website. They are on version 4.1.1.19.59 now. I downloaded the “Other Platforms” version. Then, I used the sqldeveloper-package program to install it.
sudo apt-get install sqldeveloper-package
make-sqldeveloper-package -b output \
sqldeveloper*.zip
sudo dpkg -i sqldeveloper*all.deb
Note: on my first attempt, I got this error:
dpkg-checkbuilddeps: Unmet build dependencies: debhelper (>= 7)
I fixed that with:
sudo apt-get install build-essential
Meld is an important tool for comparing text files. I use it mostly for comparing source code or programming-related projects, so it fell under this category. It’s an easy install from the Software Center.

Labor Day Weekend made for the perfect time to get my laptop updated. I know Ubuntu 15.04 (Vivid Vervet) has been out for a while, but I am just now getting it installed. Here are my notes.
I didn’t take screenshots of all of the steps. They were pretty straight forward. The one thing that I did change was the partitioning. I read that having the Swap partition on the SSD drive will wear it out, so I went ahead and moved it onto the regular drive.
So, here’s what it looked like:
In previous installs, I was using Duplicity/Deja Dup. This time, I have been using BackupPC for backups. It is a nice centralized solution that de-dups and compresses nicely.
Now, to restore… The BackupPC FAQ: SSH Setup is a good place to start.
To troubleshoot, I went to the backuppc server, and ran:
$ ssh pistachio ssh: connect to host pistachio port 22: Connection refused
That tells me that the ssh server is not installed. So, I ran:
sudo apt-get install ssh
On the BackupPC server, I had already run the keygen. So, I just had to open the id_rsa.pub file and copy it’s contents.
sudo vi /var/lib/backuppc/.ssh/id_rsa.pub
Then, on my laptop, I pasted it onto the end of the authorized_keys2 files (which, in my case I had to create):
$ sudo mkdir /root/.ssh $ sudo vi /root/.ssh/authorized_keys2
Next, I tried to connect to my laptop of the backuppc user on the server:
sudo su - backuppc sudo ssh root@pistachio
I had to run:
ssh-keygen -f "/var/lib/backuppc/.ssh/known_hosts" -R pistachio
These are the directories that I restored from my backup:
From here, you can see all the steps that I took in this series, or the next step is the Utilities and Configuration.
I’ve done some more work with Polymer 1.0, so I have some more to share with what I have learned. Specifically, what I was working on was making my home page mobile friendly and also working on a quick program with my son to track license plate states on our road trip.
