Hello i'd like to know how to remove 2 apt things that gets an error any time I type apt-get update here is the output at the end   `W: Failed to fetch   HttpError404  W: Failed to fetch   HttpError404 ` I've already tried ppa purge and apt remove neither worked.

PPA seems to be constantly offline. Whenever I use sudo apt-get update, this error is shown:  W: Failed to fetch http://ppa.launchpad.net/ 404  Not Found   How do I fix these errors?

How can I fix this? I can't update anything at all.   I've tried to switch to my best server in the options.  When I do sudo apt-get update, this is what I get:     W: Failed to fetch     Unable to find   expected entry 'universe/binary-1386/Packages' in Release file (Wrong   sources.list entry or malformed file) E: Some index files failed to   download. They have been ignored, or old ones used instead.*   When I do sudo apt-get upgrade, I get this:     Reading package lists... Done      Building dependency tree             Reading state information... Done      0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.   the contents of my source.list:     deb  quantal universe restricted main   ....update: when I update, it looks for 'universe/binary-1386/Packages'  however, if I go to: ubuntu.mirror.rafal.ca/ubuntu/dists/quantal/Release with Google Chrome, I see that the file is actually named "universe/binary-i386/Packages" (it's with an i, not a 1) . how can I fix this and make it expect the proper package?

what is the usage of apt-get -f install . when I run sudo apt-get update I got some errors at the end It says try apt-get -f install. What is this command?  the last part of my error is :   . . .   going to be installed   E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I've added many PPAs using the add-apt-repository command. Is there a simple way to remove these PPAs? I've checked in /etc/apt/sources.list for the appropriate deb lines but they aren't there.   This is on a server system so a command line solution would be great!

I have a local mirror (created with debmirror), and when I run apt-get update after a few days, I get this:  E: Release file expired, ignoring file:/home/wena/.repo_bin/dists/sid/Release (invalid since 14h 31min 45s)   How do I work around that?

I just typed   sudo apt-get remove python2.6   I didn't realized that this command will uninstall the whole packages from my computer. Is it possible to uninstall the ubuntu without CD. Or how can I fix this big mistake?

I'm trying to update from ubuntu 12.10 lately but I keep getting the "Failed to fetch" error.  W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/quantal-security/Release  Unable to find expected entry 'independent/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/quantal/Release  Unable to find expected entry 'independent/source/Sources' in Release file (Wrong sources.list entry or malformed file)  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/quantal-updates/Release  Unable to find expected entry 'independent/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/quantal-backports/Release  Unable to find expected entry 'independent/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)  E: Some index files failed to download. They have been ignored, or old ones used instead.   I changed the server and deleted the source lists from /var/lib/apt/lists/ like some answers say but still. This is really annoying.

On Ubuntu 18.04.2 LTS, I completely removed/uninstalled my apt-get because of problems I was having.  I tried re-installing it with dpkg by runnung:   $ sudo wget http://archive.ubuntu.com/ubuntu/pool/main/a/apt/apt-transport-https_1.0.1ubuntu2.23_amd64.deb   to install apt-transport-https then it's dependency:  $ sudo wget http://archive.ubuntu.com/ubuntu/pool/main/a/apt/libapt-pkg4.12_1.0.1ubuntu2_amd64.deb   then I ran the two following commands  $ sudo dpkg -i libapt-pkg4.12_1.0.1ubuntu2_amd64.deb $ sudo dpkg -i apt-transport-https_1.0.1ubuntu2.23_amd64.deb   but when I try run apt or apt-get I still get the error     command not found   I'm still pretty new to ubuntu and I'm not sure what to do

How do you completely remove ubuntu-desktop along with all installed packages with it? I'm using Ubuntu 14.04 server on vps and used sudo apt-get install ubuntu-desktop to install.

What are the differences between apt-get, aptitude, and synaptic, and which one is the recommended choice for normal day-to-day package management?  This is a basic question, but I think it'd be good information to have on the site, and besides I am relatively new to Ubuntu so I could use an expert explanation.

apt-get has a few options which looks the same to me: autoclean, autoremove and clean. What do each of them do?

I have some questions about the APT package manager.     As I understand we have repositories URLs located at /etc/apt/sources.list and /etc/apt/sources.list.d/*      When apt-get update is called, apt tries to connect to all specified repositories in the file and download information about those repositories about what programs are available and so on.      It caches all retrieved data locally in order to use it later without making internet requests to the repository.      When apt-get install is called it searches local cache package list from available repositories and if package is not found it does nothing except display an error.      apt-get search also looks into local cache and doesn't make any requests to the internet.      Am I right? I am not sure about commands that make requests instead of searching data in the local cache.        Also, what is the difference between apt-cache search and apt search? I can guess they both use the local cache.

Yes, I'm a moron, and I tried to manually install a higher point release of python 2.7.16 to /usr/bin/  (i did ./configure --prefix=/usr) on my Ubuntu 16.04 machine. It seems to work fine EXCEPT for packages that depended on python, like apt-listchanges, which fails with messages like ImportError: No module named apt_pkg  there's no make uninstall available, I've tried manually removing files, and still when I try apt --reinstall install python, Nothing gets overwritten and the python executable still gives the new 2.7.16 version...   Any idea how to get the official repository version back??

I normally use Software Updater to keep the system updated. However I occasionally will run apt-get upgrade from the terminal and I've notice there are times when Software Updater says there are no available updates but apt-get update shows some updates to packages.  I haven't been able to figure out why.
