I recently ran into the following error in Ubuntu (v 13.10).
E: Sub-process /usr/bin/dpkg returned an error code (1)
Due to this error i was not able to run the update. Here is the fix to this error.
$ sudo apt-get remove install-info
Then run this command to clear apt archives:
$ sudo apt-get clean
Then finally run
$ sudo apt-get update
$ sudo apt-get upgrade
First of all download Google App Engine SDK for Linux.
Extract it anywhere within your local folder. It can be anywhere such as in your home directory or Documents directory.
Open terminal (ctrl+alt+t) and navigate to your home directory and open .bashrc to edit with this command:
$ sudo gedit .bashrc
At the end of the file, add these lines by changing the directory to your google_appengine folder. The first line is just a comment and in the second line /usr/local/google_appengine is the path to the google_appengine folder.
### Added for GAE
Now restart your computer and then you should be able to use $ dev_appserver.py command from anywhere.
Because i am not a big fan of Ubuntu’s Unity, i am using Gnome desktop environment in Ubuntu 13.10. I have a shortcut for Chromium, Firefox etc in the Gnome launcher.
But when i tried to remove the launcher from there. I was not able to remove, when i right click on the icon i only saw Launch and Properties option.
Then finally i was able to remove it. To remove the icon from Gnome launcher just hold on Windows + Alt key then right click on the launcher icon. Now you will see Move and Remove from Panel option.
Click on Remove from the Panel then remove the launcher which you do not prefer to keep.
I was changing the hostname in Ubuntu 13.10 but after changing the hostname i got this error: “sudo:unable to resolve host Sudeep-Inspiron-3421”.
I got this error because we need to have same hostname in both the file(hosts and hostname). To fix this error type the following in the Terminal to open the file and write the same hostname in both the files (hosts and hostname).
sudo gedit /etc/hosts/
In this file generally the hostname in written in the second line. You will see the first two line similar to this:
Next enter this in the terminal and write the same hostname written in previous file.
Now restart your computer and you will not get the error.
