comment Ubuntu 15.10 identifies itself as Kali 2 after dist-upgrade
Sounds like you added a repo you shouldn't. Did you add the Kali repositories at some point, or make any changes to where your system gets its software?

comment Boot Ubuntu without screen (Teamviewer)
TeamViewer does not work unless you have an actual screen. It sounds to me like you instead want to set up some kind of Remote Desktop or VNC server so you can connect that way (which doesn't require the screen to be present on the computer, but needs you to have at the very least turned on the computer).

comment Unable to mount windows share under vmplayer 12
There is a known bug in the VMware Tools where it doesn't work with certain kernels; this is a known issue that has no resolution at this time.

comment Where is my bug report sent?
The message shown here seems that you've sent an error report, which does not always create a bug. Very rarely, does "Send Error Report" trigger a bug being created, as errors get reported to errors.ubuntu.com (of which only certain people can see the data incorporated in the error reports)

comment How to tell what PHP 7 version is installed, and how to update it to latest version?
@clearkimura You should read my answer - you'll see it's from a PPA and not a package in the standard repositories.

comment Cannot ssh as root to my virtual machine
Is the VM running inside VirtualBox / VMware with "NAT" style networking, or is it connected direct to the network through a Bridged interface or similar?

Also, multiple questions in a question is not the way to go... separate your questions into separate questions, in my opinion.

comment Isn't sudo extremely unsecure?
@user438846 Escalation privileges are cached per-user, so if 'sudo' was run and then in the same session the user executed the code you provided, then it would inherit that 'allowed to escalate' privilege. To that end, it's the timing of execution and the configuration in place at fault, or rather the defaults, which don't necessarily equate to sudo being insecure.

comment Isn't sudo extremely unsecure?
@kos However, consider the question here - it asks if 'sudo' is extremely insecure - this only can be answered within the defaults of the setup, because the user doesn't know/understand the backend configurations by default. The balance between security and usability is likely why the default was decideded this way - we're going to have to keep in mind that. Having said this, this shouldn't be closed as a duplicate, but it should be closed as broad, potentially, now that I look at it again.

comment Package signing for commercial application
.deb and .rpm packages are PGP signed, not PFX signed. I know of zero packages which use a Windows certificate to sign packages with.

comment Isn't sudo extremely unsecure?
@muru and close voters: I would say "related", not "duplicate", as it's not asking about the credential caching, it's asking whether that is an insecure in its current default, and explains the actual problem they're observing, as well as puts in the place that convenience vs. security, and that experienced sysadmins will harden their systems correctly.

comment why I cant delete any folder within /usr/local
@JIri then edit your question to specifically state that's what you're trying to remove - your question asks about /usr/local and NOT about anything inside it, so your question is incorrectly stated, and won't ever be able to be answered the way you need it to be answered.

comment why I cant delete any folder within /usr/local
@JIri what directory is it? why do you want to remove it? You should not be messing with that directory in any way, shape, or form unless you know what you are doing.

comment Why Ubuntu lags so much in VMware
If this is the Unity version, it's very slow inside VMs, and therefore not too usable - I'd suggest Lubuntu if you want to run Linux inside a VM...

comment What is the default password for the `tomcat7` user on my system?
@Gerli they're called 'system' accounts, and are usually used for system daemons (such as Apache or nginx which use www-data by default, or PostgreSQL db server, which uses postgres, or MySQL which uses mysql, etc.). They don't typically have passwords because only system daemons and services tend to use them...

comment ubuntu server cannot update. why?
Check the "Possible Duplicate" link in my other comment. Follow "Option 2" in the accepted answer there. It details how to fix the issue. But I strongly advise you to not use that repository, as it is built for Debian and not Ubuntu, which can introduce further breakages into your system

comment ubuntu server cannot update. why?
DO NOT use a Wheezy repository for Ubuntu - this will break things, even if it IS from dotdeb.
