ln: creating symbolic link `./yaml-mode.el': File exists

[Skully]

TEST CASE:
1. Install karmic version of yaml-mode
2. Upgrade to lucid version
3. Should fail
4. Reinstall karmic version
5. Upgrade to lucid-proposed version
6. Should not have an issue

-----------------

Binary package hint: yaml-mode

The yaml-mode postinst script will attempt to create a symbolic link to yaml-mode.el, but fails if it already exists.

Purging and then reinstalling yaml-mode appears to be a viable workaround.

The upstream package yaml-mode 0.0.5-2 contains a fix. Unfortunately, Lucid users are stuck with an older version.

This interrupted the upgrade from karmic to lucid (I'm sorry, I don't have exactly how logged). A manual reinstall attempt at the commandline gave me:

which I'm assuming is the same failure the upgrader hit. Purging and then reinstalling got past this.

[Fjodor (sune-molgaard)]

Got it too...

[Andrew Svetlov (andrew-svetlov)]

The same for x64 architecture.

[draptik (patrick-pdrechsler)]

Purging and reinstalling fixed the problem for me (also on x64).

Right! I too was upgrading from 9.10 to 10.04 (now "Linux owyhee 2.6.31-21-generic #59-Ubuntu SMP Wed Mar 24 07:28:56 UTC 2010 i686 GNU/Linux")

I did
apt-get purge yaml-mode
apt-get install yaml-mode

and emacs23 yaml-mode works now.

[Michael Vogt (mvo)]

It fails with emacs22

[Charles Marslett (charles-marslett)]

fails with emacs22, purge and reinstall seems to work too.

[andi bachmann (bachmann)]

purge and re-install worked for me. (emacs23)

Posted a backport request: bug #701421

[Micah Gersten (micahg)]

Should be fixed in Maverick and higher

[Micah Gersten (micahg)]

Uploaded to lucid-proposed, waiting for review

[Martin Pitt (pitti)]

Hello Skully, or anyone else affected,

Accepted yaml-mode into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Ubuntu Foundations Team Bug Bot (crichton)]

The fix for the this bug has been awaiting testing feedback in the -proposed repository for lucid for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now the package will be removed from the -proposed repository.

[Micah Gersten (micahg)]

I attempted to verify this, but following the steps in the description, I was not able to verify the initial failure. Unfortunately, I don't have time to dig into why either the steps aren't right or why it didn't fail.

[David Millett (d-millett)]

Do not worry about. I've since been able to update that laptop. Thank you for trying.

The version of yaml-mode in lucid-proposed has been removed as this bug report was not verified in a timely fashion.
