comment Are ubuntu packages (deb-files) only md5sum secured?
The prepared PDf files have random data and are only 104kb with all this effort. Why would you say this is impossible then? There must be tons of files in deb packages being >200kb where it must be possible to do such a thing. I feel not so safe after having seen the proof of concept , that amazed and shocked me

thank you for the answer. I think it is a good reply, in the sense that it gives more light to the whole background :) Unfortunatelly "Stack...Ask Ubuntu" is sometimes hard with "strictly reply to the question only" and so its great you took courage to elaborate on the topic.

@chronitis thanks for the link there. Indeed the SHA-* hashes are mentioined there I still have to figure out how they appear in the packages (which I did not see yet) or the packages system.Do you know more? Well the indication is already a good step

comment Get the default Firefox profile directory from bash
you can du a firefox; sudo lsof | grep [username] | grep firefox | grep profile which would get a firefox instance running. lsof will show you the opened files; grep will filter you out the interesting parts of lsof. This will quickstart the info + needs some fine-tuning. What do you need the information for anyhow? Do you wanna put some stuff automatically in a firefox profile folder - why?

comment how to connect to wireless network through terminal
your answers helps -already- half the way. I think it would be great and maybe help further if you added some insights to use iwconfig ìwlist and wpa_supplicant, which are usedful/necessary. Especially when wanting to connect to a wireless router that uses some encryption. I assume the question asker would need more than just enabling the device at least the user wrote "connect wireless" in the question

comment How can I convert my live Ubuntu 12.04 installation into a bootable version for CD or USB?
I think rsync or dd are better ways to shift your working ubuntu aprox 4GB+ system to a USB-stick. I am unsure CLONEZILLA will bring you instand success. Indeed the few things to get linux/ubuntu are normaly (1) a parititon layout, (2) a partition for your system, (3) copy of the -already working- system via rsync, (4) a installed and configured grub to get it to boot. I will try to find some turorial to post here later.

just some quick thoughs. (1) why iso? they do not make booting easier, rather more difficult. (2) if you have already a 4GB working root filesystem. => create a fitting partition layout on the usb stick. use dd command to image the parition to the newly created one on the USB stick. Finally install grup on the MBR of the stick and edit the grub.cfg to meet your setup. (3) if you wanna swap on SSD, why not putting Ubuntu on that thing right away? USB-Stick are not really write-durable!

Would be nice to clarify (1) Do you want to have the whole system on the USB-Stick or would you rather use the USB-stick for booting the Ubuntu only? (2) at the moment your PC harddisk has windows 8 and ubuntu? Or clearer, where is your Ubuntu install at the moment? Where will be windows 8? Consider also that using a flash-drive for system the system could be wearing down the flash of the stick. USB-sticks only have so and so many write-cycles. Flash-drive durability is not comparable to a SDD. But, of course it can be done.

comment Dual-boot Ubuntu 12.10 on UEFI along Windows 8 (GRUB - error: can't find command drivemap)
Did you do a backup beforehand? i.e the windows 8 start/system partition is something small like 150-350 MB so maybe you did dd if=/dev/sda1 of=/media/some_usb_pendrive/backupfile? If such a backup exists I would restore the windows system/start partitio which might have been "damaged".

I like the linked question about the "fallback profile". Seems you also put a bounty on it. Great! I have a very poor repu, so I cannot join, elsewise I would consider.

comment Is apparmor actually working well enough?
@stonedsquirrel: I really appreciate your input. really. I think I have to life with some downvoting witout giving the chance to let a topic "grow". Or maybe worse without understanding? So I can be happy to had your inputs, which made a closed question still a success to me :) I still wonder why we let the chance of MAC go so easily and I am conviced Ubuntu is less safe than possible. I am not a maintainer I cannot coplain really, yet!

comment How does AppArmor deal with non-profiled Programs?
@jrg: (1) Nice list (few packages covered though..:( (2) The irony is that LXC says this: "sorry not safe yet". Kind of defering the purpose of using a "linux container" in the first place, when its rather likely to be not safe. At present I cannot manage to get Ubunut safe neither via LXC nor AppArmor.
