    Unhappy 12.10 installation failed

    I have a dual-boot system: Windows Vista 64-bit and Ubuntu 12.04->12.10 (attempted)

    My 12.04 system was ok; but, as recommended (bug fixes, improved security,etc.) I attempted to upgrade to 12.10 about 6 hours ago.

    1. There were some errors generated during the installation and when prompted for feedback on these to Ubuntu developers I tried to do this.
    2. I am quite sure that I followed the instructions during the upgrade process correctly.
    3. I can boot-up 12.10; but, unfortunately, I am unable to connect to the internet via my wireless. [Note, this was no problem before I attempted the upgrade.]
    4. I tried to use the recovery mode for 12.04 but, this was impossible --- kernel was missing, etc.
    5. I was unable to recover (return to) any of the earlier versions of Ubuntu.

    I have all the details on my wireless connection (saved this from 12.04) and it seems no matter what I try I can not connect to the internet with 12.10.

    Questions:
    1. How can I connect to the internet with 12.10?
    2. Why are these recovery modes offered as possibilities if they do not actually work properly?
    3. How can I recover 12.04?

    Note:
    1. I am sending this from my Windows Vista system.
    2. I can provide details of my wireless connection (if this would help) and any other information that might be useful for recovery of 12.04.

    Recovery of 12.04

    I tried to installed 12.10 very recently; but, there were several errors during the installation and I ended up with a 12.10 that did not provide an internet connection.

    No matter what I attempted with "Network tools" I never managed to connect to the internet via wireless. Connection to the internet was never a problem with 12.04.

    I then tried to recover (generic mode) 12.04 but I get the following error messages:

    error: file not found.
    error: you need to load the kernel first.

    Press any key to continue...


    If I try to recover 12.04 (recovery mode) I get the following

    Loading Linux 3.2.0-27-generic...
    error: file not found.
    Loading initial ramdisk...
    error: you need to load the kernel first.

    Press any key to continue...


    How can I recover my previously working 12.04?

    I hope that this will help in fixing this problem.

    Re: Recovery of 12.04

    How can I recover my previously working 12.04?
    Only by a fresh installation, because downgrading is not supported.

    but, as recommended (bug fixes, improved security,etc.)
    I am wondering where you read this. It is simply wrong. 12.04 is a LTS and will get full updates and security advisories for 5 years. Of course, you probably won't get newer versions of software, but the software for 12.04, on the other hand, should be more stable.

    1) What then is the purpose of having "recovery" to earlier versions in the bootup menu?
    2) How can I do a fresh installation of 12.04 while keeping the applications and configuration that I had before my attempt to upgrade to 12.10?
    3) When do you think it would be safe to upgrade to 12.10?
    4) What precautions should I take to prevent this from happening in the future?
    5) What does LTS mean?

    This message (on importance of upgrading) came from a message that I often see with Microsoft's upgrade manager when checking for updates. I have also read something similar in a book on programming (don't remember the name of the book unfortunately).

    Re: Recovery of 12.04

    1) What then is the purpose of having "recovery" to earlier versions in the bootup menu?
    This just refers to previous kernels, NOT the whole previous operating system.

    2) How can I do a fresh installation of 12.04 while keeping the applications and configuration that I had before my attempt to upgrade to 12.10?
    Reinstall the applications, because a fresh install removes everything. Settings could be kept if /home is on a separate partition, but I doubt that it would make sense. 12.10 has newer applications and therefore maybe settings not present in 12.04, so probably more trouble than it is worth.

    3) When do you think it would be safe to upgrade to 12.10?
    I don't know. With a release cycle of only 6 month there is not much time to fix bugs and issues, and many of the developers are already working on the new release.

    4) What precautions should I take to prevent this from happening in the future
    If you prefer stability over bleeding edge, stay with LTS versions. If you absolutely need the latest and greatest, learn to live with the fact that there will be problems.

    5) What does LTS mean?
    LTS means Long Term Support. These releases appear every two years and will get extended support. For example, for 12.04 it is planned to support it for 5 years, while a normal release, in theory, gets support for only 18 month.

    Ok
    Thanks very much 2F4U!
    I will try to do a complete reinstallation on by dual-boot system. I have downloaded 12.04-1 and burned an DVD for it. And I will stay with 12.04 for a few more years, as suggested by you.

    Finally, this is something that I have never tried before --- are there any special things that I should do or not do to avoid problems when downgrading from 12.10?

    Note, I have a dual-boot system (Windows 7 64-bit and Ubuntu 12.10).
