I'm using Ubuntu 10.10. I want to upgrade it to the latest version but I'm just unable to do so. When I press Alt+F2 and write 

upgrade-manager-c-d

and run it, it says 

Error stating file '/home/ann/upgrade-manager- c-d': No such file or directory`

What should I do?

  • upgrade-manager-c-d was given in the help section. – Annie Jul 31 '14 at 06:54
  • Are you sure re-installation is the only solution left? – Annie Jul 31 '14 at 06:54

    At this point, installation of 14.04.1 is the fastest, easiest and safest option. If you really wanted to upgrade for whatever reason, you'd have to upgrade 10.10->11.04->11.10->12.04->14.04 and apply the fix that @Rinzwind mentioned. But you'd likely end up with broken configurations and tons of stuff to fix, so I absolutely do not recommend it. Just reinstall, you'll save yourself a lot of trouble. – jmiserez Jul 31 '14 at 07:07
  • Seems like i've gotten my answer. Thank you all for the help. – Annie Jul 31 '14 at 07:09
  • Agree with jmiserez. First backup your data, take note of any applications settings; and check you have all passwords, settings, etc. recorded somewhere. Then do a new install of 14.04.1. If you only have 2GB (or less) of RAM, user 32-bit. – david6 Jul 31 '14 at 07:52

You're misspelling the command (and also passing flags to it incorrectly).

Don't run upgrade-manager-c-d. Either:

  • Run update-manager -c -d instead, if you want to perform the upgrade with a graphical utility. (This is probably what you want.) That is, the command contains the word update rather than upgrade, and spaces before the dashes are required. Or
  • run do-release-upgrade -d instead, if you want to perform the upgrade entirely from the command line.

(There are two main causes of confusion surrounding when spaces have to be used in commands, in Ubuntu. You might have intended to type the command with spaces; that is, it might a typo. Or you may be used to Windows, where command-line flags starting with / needn't be preceded by a space. For example, dir/s and dir /s have the same effect, on the Windows command prompt. In Ubuntu, flags starting with - do need to be preceded by whitespace.)

Also, it is odd that it looked for the command in your home directory. This suggests you may be starting the command with something like ./, that is, that you may be running, ./update-manager. Basically the only time you need to start a command with ./ is when you are deliberately attempting to execute a file you know is located in you current directory and not provided as part of Ubuntu.

Since Ubuntu 10.10 is end-of-life (and has been for some time), you will probably need to follow these instructions before attempting the upgrade:

That explains how to add the old-releases software sources. Since 10.10 is so old, you may need to perform multiple upgrades: 12.04 is the lowest release with current desktop support.

  • 10.10 → 11.04 → 11.10 → 12.04.

Once you get to 12.04, you can upgrade to 14.04 directly (if you wish), since 12.04 and 14.04 are both LTS releases. Or you can stay with 12.04--because it is an Long Term Support release, it won't go end-of-life until April 2017.

Especially if your Ubuntu system is only lightly used and lightly customized, you might prefer to reinstall than to perform multiple upgrades. You should of course always have backups made of documents and other important files, but if you decide to reinstall Ubuntu, it's especially important that such backups exist and are current.

You should do a fresh install buddy otherwise you have to go through number of intermediate versions before you reach latest version.

You should either go with latest long term supportted Ubuntu 14.04 or latest yet to be released Ubuntu 15.10 (to be released on October 22 this year). Don't install Ubuntu 15.04 because it will lose support on this October 22 when Ubuntu 15.10 will be released.
