comment Ubuntu latest LTS is now released, why can't I upgrade from previous LTS? And how can I force the upgrade?
Good answer, but could do with an explanation to go with "I do not recommend", so that readers aren't just taking your word for it.

comment Does Ubuntu damage USB drives?
I get the popup in 14.04 (Linux Mint KDE edition) whenever I eject a USB drive, and also my 15.10 Kubuntu machines. Not sure about 15.04, but I would assume so.

comment If I dual boot Windows 10 and Ubuntu, could a keylogger affect me if i'm on Ubuntu?
If the malware has read access to the hard drive, then it can do whatever it likes. It is only limited by the author's skill and imagination. "Windows does not support ext" is almost meaningless in this context as that doesn't prevent the malware supporting it (not to mention other attack vectors e.g. infecting your hardware's firmware).

comment How do I convert an MP4 to an MP3?
On a relatively fresh install of Ubuntu 15.10, this crashes almost every time I hit the convert button. Shame, seemed like a good program otherwise.

comment Is there any guarantee that software from Launchpad PPAs is free from viruses and backdoor threats?
Regarding your second paragraph, I think you misunderstood the OP's intentions. He was not suggesting Pidgin has a backdoor. He used it as a hypothetical example to illustrate his question.

comment How to install Cambridge dictionary without wine?
The first sentence is not technically correct. An open source software which was never intended for usage on Linux could be re-compiled for Linux depending on how portable the code is (albeit that doesn't apply to the OP's requirement).

comment Is there any simple way to access installed programs?
@LinuxBill This does not answer the question at all. It explains how to search for an app by name, which the OP clearly explained he already knows. He wants to browse his installed software, without knowing the name in advance. Like a launcher menu in KDE, Windows, etc. I'm not sure how this wasn't completely clear from the question.

comment How to disable strict host key checking in ssh?
@qwertzguy It does work. Your option will make it so that the host key is lost each time, which is useful and more secure, but not what the question asked for.

comment Security risk in everyday use of an admin account (not root)?
@TripeHound Alternatively, you step away from the computer for a bathroom break, having just authorised a sudo command, and someone else steps in. I don't see a distinction in risks between potential or otherwise - the word risk merely implies that there is some non-zero probability of an undesirable outcome. Yes, in normal circumstances you would notice the password request. Does your attacker, who planted that script on 1000 computers and doesn't have a specific target in mind, care?

comment Security risk in everyday use of an admin account (not root)?
On your point regarding getting the second password just as easily, that doesn't have to be the case. I manage my desktop machines with Ansible, which connects to an admin account via ssh. The user accounts do not have sudo privileges, and there is no need to ever use an admin account physically on the desktop (in fact it is undesirable, because I don't want my machines being messed with individually and falling out of sync with the rest).

@ByteCommander That only works if you have physical access to the computer.

comment What are the consequences of removing metapackages?
As for administration, upgrading versions, etc. - I intend to manage my servers using my choice of configuration management tool, so its hard to imagine a use for ftp or telnet. If I do need them later, reinstalling them isn't an issue. I still like Ubuntu as I like the comfort of having updates provided by a reputable and stable distribution.

comment What are the consequences of removing metapackages?
Thanks for the answer. To address the "why" part - disk space is not a consideration for me. It is more a matter of (a) I dislike things I can't understand. Reviewing and deciding the fate of each and every package on my system helps my learning process, (b) as it is a server, I want it minimise all possible attack vectors. A ftp client is unlikely to be vulnerable, but paranoia never hurts when it comes to security, and see (a) - I would prefer not to spend mental effort ascertaining if a package may or may not present a security risk, when I can simply delete it.

comment how to recover deleted files by ubuntu
You should make clear in the answer that the OP should not attempt any of this from within his Ubuntu installation on the drive he wants to recover from. He needs to do it from a live disc.
