How can I delete Ubuntu temp files which are created during software installation or upgrade?

Question

I make a very big mistake with my Ubuntu. I was try to install Ubuntu touch but disk disk has no space. My mistake is I not read/ neg-late need of primary requirement of space for installation of Ubuntu touch. Because of full disk space my Ubuntu does not start. I try to free more than 2 GB space by deleting media files. But after start Ubuntu that space also allocated or used by Ubuntu. I use commands

sudo add-apt-repository ppa:phablet-team/tools
sudo apt-get update
sudo apt-get install ubuntu-emulator
sudo apt-get upgrade
sudo ubuntu-emulator create UbuntuTouch --arch=i386 --channel=ubuntu-touch/utopic-proposed

when I use that commands during instalation process my Ubuntu is freeze and hang so I restart it but after restart it does not start. for solving that problem which files should I delete? suggest files or folder for delete which make free space but their delete not make cause of system failure. I don't like format my Ubuntu System.
Note
I have dual boot system in EduBOSS Linux I has full root privilege. I can access Ubuntu files by EduBOSS or BOOT repair disk.

Solution

I would try to clean the repository of downloaded packages. Either of these commands (see man apt-get).

apt-get autoclean
apt-get clean

If you don't have /tmp on tmpfs, you may want to delete all the files and directories under /tmp. A tool like tmpreaper can be used to keep it clean. You can also set edit /etc/defaults/rcS and uncomment the TMPTIME=0 line to have /tmp cleaned on reboot.

If you can't boot fully, you can try booting into recovery mode. If you can boot that far, you will need to mount the disk in read-write mode before cleaning it up. Running the command mount -a should mount all the file systems so you can do cleanup. Once you are done reboot.
