comment How do I install Adobe Acrobat Reader deb package downloaded from Adobe website?
In 14.04 to avoid some warnings I had to do: sudo apt-get install libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 ; apt-get download overlay-scrollbar-gtk2:i386 ; sudo dpkg --ignore-depends overlay-scrollbar:i386 -i overlay-scrollbar-gtk2_*_i386.deb ------ It is not possible to use sudo apt-get install overlay-scrollbar-gtk2:i386 because this package depends on non-existing overlay-scrollbar:i386. ------ Also libdconf0:i386 and libdconf-dbus-0-0:i386 should probably be installed but they are not available in 14.04.

comment How can I capitalize letters before a certain character? (^)
With GNU sed the second variant of the regex (extended regex) can be used with option -r: sed -r 's/^(.*)\^/\U\1/'

comment ifdown in cron bash script fails to run
1. Does the script (and ifdown) hang or end prematurely? (Do you see it in ps -ef?) It should hang if your script does not continue. ------ 2. Try to use the verbose switch to get more information: ifdown -v eth1 ------ 3. Does it fail if you manually restart cron? Try sudo service cron stop && sudo service cron start ------ 4. What are the exported environment variables in the working and non-working case? Store the output of export. If the non-working case is missing some variables which could be important, try to set them in your script.

comment no login screen ubuntu 14.10
If you end up recovering just your data you can boot Ubuntu as a live OS from the installation USB or CD. There you can mount your partition on the computer's hard-drive and backup your data. Then you can do clean install and copy the data back. --- If you chose non-LTS version (like 15.04 or 14.10) then you should upgrade twice a year. I personally prefer to stay with the LTS version for two years or longer.

comment Firefox stuck on old version and problems with held packages
Does sudo apt-get update show any errors or suspicious output? What do you have in the file /etc/apt/sources.list?

For users which are not Linux or IT enthusiasts it is certainly recommended to stay with LTS releases of Ubuntu like 14.04 and in the future 16.04.

comment no login screen ubuntu 14.10
You can try to test if the system is functional with only the graphic screen (X Server) black: Try to switch to the text console using Ctrl+Alt+F1. If the login prompt appears you can try to login. From the shell in the text console you can safely turn off the computer using sudo shutdown -h now. --- BTW do you know that 14.04.2 is a release with long support (LTS), that this update of 14.04 was released after 14.10 and that support of 14.10 will end in July?

comment WiFi not working on HP Probook & HP 431 Notebooks
To run a command as root in Ubuntu you run it with help of sudo . In your case: sudo rfkill unblock all. --- Also it could be interesting to know if you installed the original Ubuntu 14.04 or the current 14.04.2 with updated Linux kernel.
