I bought some issues of the Linux Format magazine on the Ubuntu Software Center. I now reinstalled Ubuntu and would like to redownload the magazines. In the list, they correctly appear as "Previously Purchased", but if I try to install them, I see:     There isn't a software package called lxf171 in your current software sources.   Also, the magazines do not appear when I click on reinstall previous purchases in the menu.  If I try to buy a new issue, everything works perfectly.  Does anyone know how can I download the magazines that I already paid and donwloaded in the past?

After a reinstall of Ubuntu 12.04 ,it's impossible to install commercial games, e.g Oil Rush. It gives this error:  Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-amd64/Packages  The requested URL returned error: 401 Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-i386/Packages  The requested URL returned error: 401 Some index files failed to download. They have been ignored, or old ones used instead.   I bought these games in 11.10, but I installed these games in 12.04 before... How can I solve this problem?

I just installed Ubuntu 14.04, and Ubuntu One isn't installed by default and their download page says it comes pre installed, which doesn't help with anything.  I wanna move all my files from Ubuntu One to Dropbox, but downloading one file at a time from the browser and upload it again to dropbox will take way too long.  Is there any way to get Ubuntu One on Ubuntu 14.04? or somehow download all files from the Ubuntu One website?  I see they updated their site:

There was recently another release of , but it is  a pain to have to manually go to their website and download the packages every time there is a new release. Is there a PPA that always has the latest version of LibreOffice?

In Ubuntu 17.10 I installed applications from the software center. At first everything worked fine, but after a few days they kind of disappeared. They are neither found when searching in the dash, nor when the executable name directly in the terminal. However, the software center shows them still as installed and they can be launched from there. Any help to fix this strange behavior is appreciated.

When I start the Ubuntu software centre, it says I cannot do anything until the package catalog is repaired. However, repairing fails.  I ran sudo apt-get -f install and found the problem to be:  mysql-server-5.5 depends on mysql-server-core-5.5 (= 5.5.24-0ubuntu0.12.04.1); however:   Version of mysql-server-core-5.5 on system is 5.5.28-0ubuntu0.12.04.2.   So, the question is, how do I install that version and resolve the dependency problem?

This question seems to have been asked  already. My IT department installed the OS so I don't know how to register it properly but I do have root access. Is there a way to get the same packages using the CentOS repositories maybe? I'd also like to install IceWM but without a compiler I can't even build it myself.

How can I reinstall Ubuntu 13.04 safely, without losing anything except settings? Is it possible? Or at least keep only programs and the home directory?  I want to reinstall as I have recently experienced various issues like the scrolling being very jumpy and lightdm rendering weirdly. Can someone more experienced explain how to reinstall Ubuntu as I have been searching in vain for days. Thanks in advance.

I'd love to test the latest Ubuntu alpha/beta (otherwise known as "Ubuntu+1"), but I can't find it.   Where can I find download for the pre-releases of Ubuntu?

In the Ubuntu Software Center, there are lots of $0 apps that I can 'purchase': for example:           As these applications are free (as in beer), I wonder how I can install them using apt-get.

As a developer of free software, I want to get my application into Ubuntu.  Should I provide a source tarball and ask for packaging? Or should I create a package myself? Should I target Ubuntu directly, or should I try to get into Debian and then into Ubuntu automatically?

I used sudo apt-get remove python command and accidently removed a bunch of packages that were required. I logged in via command line and installed ubuntu-desktop again but there are other packages that are missing, and I'm looking for a way to easily reinstall those removed packages. Since there's the log at software-center I wanted to ask what the easiest way might be to roll back changes or extract the removed packages list from the software center...  note: I typed sudo apt-get install .... .... ... ... for about two dozen of those removed programs in that list, but when I pressed enter it didn't install any of them because some package names couldn't be found.  The programs were removed at the same date.

Upon my observation, seems new packages will first appear in security.ubuntu.com, but if you upgrade later, they will appear in XX.archive.ubuntu.com (depends on your config),  Was that true ?

The Software Center in Ubuntu 16.04 (Gnome Software) shows only part of the packages available. While e.g. apt list qtcreator correctly lists the corresponding package a search in Software Center finds nothing.  Is there something misconfigured? I upgraded from 15.10. Until now I have used the old Ubuntu Software Center which worked fine.

Please help me.
