I just downloaded e4rat to cut down the booting time of my laptop. Right now the boot time is somewhere around 50 secs. I read I can get it down to 20 secs or even less if I'm lucky. Problem is e4rat seems won't install. When I click on downloaded file Software Centre opens up and I just click on "install" (no brainer). But after that I just get an icon on Unity bar that shows install progress without any actual progress. Appears as if it freezes. Can't click on it. When I hover over it it just says "waiting to install" and that's all. Reboot didn't help.

Any ideas what I can do ?

Hi I encountered similar difficulties with both of the software centers and external packages. I therefor use different procedures - that always work:

  • Either, open a terminal maneuver to the location of the deb-file and then run sudo dpkg -i e4rat_0.2.3_[amd64/i386].deb - use the correct corresponding architecture (no brackets). If it tells you something about unmet dependencies etc. - don't worry we will fix this with a sudo apt-get install -f
  • Or use gdebi a graphical tool for installation of deb-packages. You might have to install it with sudo apt-get install gdebi and a right-click on your downloaded package will give you the option to open it in gdebi.

About e4rat: I am not quit sure if you want to do this.

First of all for it to work you will have to uninstall ureadahead which in some way does a similar job.

Second this software has not seen any update in four years - might also be a sign the developers did great work.

Thirdly there are other ways of compressing boot times. And I would try them first. Yet further steps depend on your version of Ubuntu and might be a whole new question. Possible starting point on a brand new version (16.04 or 16.10) of Ubuntu might be the third answer in this question How do I improve boot speed?
