I tried to place an install it link into an answer, but apps.ubuntu.com went away and stopped working, it redirects to the Snapcraft store now.
The image was there all right but the link was redirected to https://snapcraft.io/store -- this isn't really what we want.
What happened to apps.ubuntu.com? Is there a new place where Ubuntu software can be found?
How can I get information about Ubuntu releases from the command line?
Items of interest
In a virtual terminal I (accidentally) pressed Win+1 and got a new line consisting of
(arg: 1)
As long as I keep Win pressed, all numbers I press get appended to the number in the parentheses, e.g. Win and 1+4 yields (arg:14).
When I (after releasing Win) press any key, that character is printed as many times as the number reads and the (arg: ...) expression is replaced by the standard prompt.
Does anybody know what happens here?
I wanted to install unity-scope-github but was faced with a surprising
The following package was automatically installed and is no longer required:
session-shortcuts
Use 'sudo apt autoremove' to remove it.
The following packages will be REMOVED:
ubuntu-desktop unity unity-scope-home unity-tweak-tool
The following NEW packages will be installed:
unity-scope-github
Now this is probably a bug in some old/not actively maintained package which will be reported as soon as I have understood the issue.
My real question: How can I see why apt reaches the conclusion that installing one additional scope requires the removal of two useful meta-packages and unity-scope-home.
Is this an indication of problems in the database?
Annotation: session-shortcuts is only "no longer required" when I try to install unity-scope-github, before this sudo apt autoremove yields no result at all.
I know unity-scope-github is quite old/not actively maintained and I can and will live very well without it
While looking at the output of journalctl -f I noticed that apparently compiz is notified about (and logs) every search I make in the entry bar (or the search bar) in Firefox (but not in Chromium).
Typing into the entry bar something like

It does not matter which search provider I have selected. I would like to know what settings cause this behavior of compiz and how to prevent this.
In my opinion it is none of compiz's business what I type into a search bar in my webbrowser.
I do know that it is possible to circumvent this by entering search expressions directly into the search field of any search provider but that's not what I am after.

Settings/Security and Privacy/Search ("when searching in the dash...") is off.
When you (with Nautilus or Nemo) access a resource that requires a passphrase you are presented with a dialogue that gives you the choices to
When you select "remember forever" the passphrase is stored in your login keyring, accessible with seahorse (also see How to make login keyring forget a password)
Now when I selected remember password until you logout I cannot find that entry in seahorse. Where is it stored?
Note: I am well aware of the possibility to simply logout/login but I still want to find the place where it is stored.
Related: Seemingly random “Authentication is required to change your own user data”
Every now and then (only after resuming from Suspend) I get the following dialogue.
The information provided is not enough for me to decide what to do (hence I cancel of course :-)
The link in the Details section leads nowhere.
My guess is that there is some program (A) asking some service (B) for permissions.
I want to know how to find out what service/program (B) generates this dialogue (hints about the program (A) requesting the permissions in the first place are welcome too :-))
Ubuntu 15.10
Further investigation spurred by waltinator's answer shows polkitd to possibly be part (B)

Thanks to waltinator's suggestion about xwininfo (which doesn't tell the pid of the window's process) I now found wininfo. So I was able to confirm that the window is created by /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1.
Now I want a way to ask polkitd/policykit which program requested which action, but that needs a new question.
On my server I want to assign several IP addresses to one NIC, but without using the deprecated ifconfig or the obsolete "alias" notation (like eth0:0) in /etc/network/interfaces because in IP Aliasing (on www.kernel.org) you can read
IP-aliases are an obsolete way to manage multiple IP-addresses/masks per interface
The system refuses to shut down or reboot while another (GUI) session is open. It simply logs me out, when I select shut down or restart from the system menu.
How is that accomplished?
I am not asking for a rationale (it is quite clear that shutting down might have adverse impacts on the work of another user) but for the mechanism behind this behavior.
On a fresh install (13.04) I see a strange mix of languages in Software Center
The menu (like my system language) is in English, but the descriptions are in German. I want the descriptions in English too.
I am using a german keyboard and have German installed too (for giving support to students with German as system language :-))
In system settings I have moved German below English - so it should be ignored, I have logged out after that.
I have cleared the "Software Center Cache" with Ubuntu Tweak. The picture remains the same.
I just realized that under 13.04 it isn't possible any more to add applications which are using the systray to a whitelist. I found the suggestion of downloading a patched version of Unity but I'd rather make one app I like (see bug report for blueproximity) use app-indicator instead.
I saw several python apps exist for application indicator, for instance ClassicMenu Indicator . So I want to try to adapt the program.
What I need now is a pointer where/how to start, maybe a few hints. (No experience with python but plenty with several other languages)
