comment Cannot install Nodejs 4 in Ubuntu 14.04
I added an answer suggesting to run sudo apt-get update but, looking the the script's source I see that it does it automatically. Removed my answer.

comment Sudoers permission without loging in as root
It's not "instead", sudo su and sudo -i do roughly the same - open a superuser shell after asking for user's password. There may be some tiny obscure differences but for the purpose of the question they're identical.

comment unallocated space added under sda3, how to add it to sda5 now (gparted)
Hmm, I'm not sure why the warning is there - I don't dual-boot Linux and Windows.

You right-click on the un-allocated space and select "New". Then you select Linux swap as the type of the new partition.

Because to resize a partition you need a continuous block of free space immediately after the partition you're going to resize. Instead of deleting and recreating the swap you can try moving it, but I don't think it's worth it because swap contains no useful data anyway.

comment Moving entire Linux installation to another drive
+1 - it's also possible to avoid booting from a LiveUSB and do everything while booted from the original drive, do all the changes, reboot, voila.

comment ImageMagick convert and low RAM
What are the dimensions of the image in pixels? "12.5Mb" does not tell much as it the size of compressed data which needs to be de-compressed to be resized. 10.000 x 10.000 pixels image would require 400Mb of RAM (4 bytes per pixel), and can be easily compressed to a few Mb if it is mostly solid color.

comment Could not calculate the upgrade from 14.04 to 15.04
You can only upgrade from one release to the next one (from 14.04 to 14.10, then from 14.10 to 15.04), or from one LTS release to the next LTS release (14.04 to 16.04 when it is out).
