TYPO3 Core

happens also in 4.7.0beta3 with Firefox 3.6x

I have the exact same error on two different servers with the latest typo3 version (4.7.2).

In addition i watched a strage behavior:

with a new typo3 installation:
- i go to the extension manager > Language Packets
- execute "Check status against repository"
- it show many available updates
- i press "update from repository"
- all updated do fail

after that, every time i execute "Check status against repository" it says gives me the status: "up to date".
I suspect that some update-flag is set even if the update fails ..

i just moved project that showed that problematic behaviour to a server where other projects are hosted for which the update process does work like a charm: the problem remained the same.

I did a test with 6.1.2:

i do have still problems:

The ajax update requests do return this error:
<b>Fatal error</b>: Call to undefined function TYPO3\CMS\Lang\Utility\Connection\zip_open() in <b>.../typo3_src-6.1.2/typo3/sysext/lang/Classes/Utility/Connection/Ter.php</b> on line <b>196</b><br />

In the first run, for every failed update a error icon appears.
When i reopen the lang update page every failed update shows "up to date"

Please look that the "update done" flag is only set after the new lang files are successfully written.
It looks like the flag is set after a successful download but before writing/extracting ..

Your error is related to a missing PHP extension, please make sure to install that.

Ok, i added zip support on my server. Updating works now.
But the previously failed updates still show "up to date" - which is wrong. Like in issue #30918

I got the previously failed updates to work by deleting the ...l10n-de.zip files manually from the typo3temp folder.

I think there should be a better error checking and logging and messaging for updating the language packs.
There are many things that can cause a problem:
- network
- php curl
- php zip
- file system write right
But if a error occurs, you do not get a useful error messages.
