TYPO3 Core

I've got the same error on 6.2.15

Hello Andreas,
maybe it was not clear what I wrote. I could reproduce this problem with only flux 7.1.2 and fluidpages 3.1.2 and no other extensions installed. fluidpages 3.1.2 has the dependency 'flux' => '7.1.0-7.1.99',

A customer of ours gets the same error concerning powermail 2.1.17 and 2.19.0, also on TYPO3 6.2.15.

Maybe a problem in the repository?

I am getting the exactly same error on an upgrade from 6.1 to 6.2.15, without any updates of extensions. Occurs after updating the repo infos, not after changing extensions.

For testing purposes I removed the newest entries of flux from tx_extensionmanager_domain_model_extension and it works again.

Maybe a problem with the upload of the latest flux update?

I can confirm this error.
It happened to me in 6.2.15 just after updating repo info.

I can confirm same error, also went through all ext_emconf and only lines with flux we have are these:
'flux' => '7.1.0-7.1.99',
'flux' => '',

we are running 7.1.0 flux right now.

It seems to be fixed in 6.2.16

We got a similar problem today: flux was requested to be downloaded in different versions (7.3.0 and 7.4.0).
Clearing tx_extensionmanager_domain_model_extension fixed the fatal error but also results in not being able to fetch from TER anymore.
Flux Version is 7.2.3, any ideas?

Similar problem as described from Marc Blasig here on a dev system which wasn't updated for a while after pulling the extension list from TER. Fixed with TRUNCATING tx_extensionmanager_domain_model_extension and updating the core to 6.2.25 and clearing all caches. Seems to be okay for me right for the moment.
