I am trying to install Kubuntu 14.04 x64 using the Wubi provided in the ISO file mounted using Daemon Tools, from Windows 7 SP1 x64 Ultimate.

I'm getting this error message:

when I am at the stage:

after launching the installation with these parameters:

Why?

I have the same issue when using wubi1510r298.exe from https://www.dropbox.com/sh/6uqomp8l1frcd1y/AAAhSCimTaYE-94egbmc1X_na?dl=0, on two different computers.

I also have the same issue when trying to install Ubuntu instead of Kubuntu.

The hash algorithm for gpg signatures has changed from sha1 to sha512 and sha512 is not supported by the used Wubi module.

I uploaded a patch to launchpad.net (source code)

The patch still does not provide sha512 support but it provides a better error handling. So it writes the following messages to the log...

WARNING saplog: A signature from ID:'46181433FBB75451' has an unsupported hash algorithm:10(SHA512).
ERROR  CommonBackend: Could not verify signature for metalink md5sums
ERROR  CommonBackend: Cannot authenticate the metalink file, it might be corrupt

... but there is no unhandled fatal error which prevents an installation.

If you want to patch an existing wubi.exe it is not necessary to build the whole wubi.exe from source.

If you copy api.py from source (source path: /src/openpgp/sap/api.py) to your wubi.exe with 7z (destination path: /lib/openpgp/sap/api.py) it should work, too.

If you don't want to patch anything, here are also already fixed versions. wubi14043.exe, wubi14043SB.exe and wubi1504SB.exe use an additional api.py . wubi1510r299.exe uses a new build from source.

I have managed to bypass this problem with Ubuntu 14.04.3 (it works 100%). You can try to run the same method on Kubuntu 14.04.3 (it should work) or analyze changed isolist.ini file (check the comments) and update wubi1510r298.exe accordingly to run newer version.

Here is the instruction (for version 14.04.3):

  1. Download kubuntu-14.04.3-desktop-i386.iso into separate directory.
  2. Download wubi14043.exe (for version 14.04.3) into the same directory.
  3. Install 7z.

  4. In the directory with wubi14043.exe create a temporary folder:

    mkdir wubi-temp

  5. Go to temporary folder:

    cd wubi-temp

  6. Extract wubi14043.exe into tmp folder:

    7z x ../wubi14043.exe

  7. Edit file data/isolist.ini and replace its content with the content I pasted below.

  8. Update your wubi14043.exe with changed isolist.ini:

    7z u ../wubi14043.exe

  9. Remove temporary folder:

    cd..
    rd /s wubi-temp

  10. Disconnect your computer from the network and run updated wubi14043.exe - it should be able to install Kubuntu from the local ISO now.

Updated isolist.ini:

  • Thanks! Luckily Wubi is supposed to make Ubuntu installations easier… – Franck Dernoncourt Nov 20 '15 at 0:48
  • Unfortunately Wubi has been officially abandoned and apparently is no longer supported even for the older [X]ubuntu versions (which should work properly). Luckily Wubi source code is available so hopefully it will always be possible to patch it and update, even when simple fixes won't suffice. – Konradzinski Nov 20 '15 at 2:00
