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?

I'm trying to figure out a way to get a list of the packages that are no longer available in the repositories that I have enabled. This workstation has been through quite a few versions of Ubuntu and has had many 3rd party repositories added and removed. I'd like to get a list of software that I have from these removed repositories, so I can clean it up or add back the appropriate repositories.

When updating, I get the following error message:   W: The repository 'http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial Release' does not have a Release file.   Here, I find another statement on this error:   This recommends removing certain PPAs; and, I'm not sure if I should do that since it might mean not getting the updates that I need.    Is this what I should do?

Everytime I sudo apt-get update it always not complete and will say in the end  E: Read error - read (5: Input/output error) E: The package lists or status file could not be parsed or opened.   Same goes, when I try to install something and do sudo apt-get install &lt;some app&gt;  What should I do ? I admit, that my drive has bad sectors, could that be the reason? Is there anything else I can do?

I am unable to apt-get install any packages because E: Package '&lt;package name&gt;' has no installation candidate. Unlike the other similarly named questions, I am using debian and I have not been able to get any packages to work due to the same error. apt is still able to list repositories. I have updated, upgraded, rebooted, and repeated after my attempts at fixing sources.list, but nothing has worked.  For example,  $ sudo apt-get install nodejs Reading package lists...

Every once in a while I see users having issues to update due to errors like this:  E:Type 'ain' is not known on line 1 in source list /etc/apt/sources.list.d/some-ppa.list'   with varying types/line numbers/source list files (often after removing a PPA).  How can such an error be fixed?

I'm relatively new to Ubuntu 16.04, and everything has been going fine until my OS threw this error today.   Below is the source code from /etc/apt/sources.list for line 54:  deb http://archive.canonical.com/ partner   I have tried appending ubuntu after the / and before partner, but this does not seem to work.   Any ideas what else to try? I can't run sudo apt-get update until this is fixed.

There are now errors when updating and I cannot install most software due to a corrupted  /etc/apt/sources.list   file. Is there a copy I can download to replace it?  The file would be for Ubuntu 12.04 (Final Beta) in the United States.
