Execution of command 'appcenter/invoke_dry_run' has failed:
Received this and the following traceback again (4.0-1 errata113 (Walle)).

Remark:
Unknown Error with Open-Xchange App Suite. I attempted to uninstall this error appeared.

command was 'apps/get'.

Comment 3 Florian Best

2016-05-28 14:18:35 CEST

Maybe fixed by Bug #40874.

Comment 4 Dirk Wiesenthal

2016-05-29 20:10:02 CEST

This is not fixed yet, just a bit more unlikely to occur since we did some performance optimizations.

Due to these optimizations, the ini files are not parsed by the old code during the very first module call (appcenter/query). So the App Center should at least load.

But as soon as someone chooses to install any non-docker App and has such a malformed ini file, the traceback should return because then all ini files are parsed.

Bug #40874 improved error handling of ini files in the new code, so this does not help. In fact, the new code was never vulnerable to this special error. This ini file has been ignored by the new code since 4.1-0.

To fix this bug as DUPLICATE/WORKSFORME, one needs to fix Bug#40064.

Comment 9 Florian Best

I think we should at least add some code around the error and raise an exception with more details (aka. the whole INI file + filename) in that case, soon.
This but is reliably reproducible on our internal UCS 4.1-4 KVM templates and pops up immediately as system-setup-boot is started.

Comment 18 Dirk Wiesenthal

For all we know, this is a timing issue where the cache is not yet ready. The specific Traceback is handled in the new code. The fix is to not use old code "immediately" if at all. This has already been done in App Center and System Setup.

This should not be fixed in old code. One may want to rebuild 4.1 DVDs (and all Appliances?) so that System Setup is not affected.

OK, as far as i understand, these errors come from the old u-system-setup (pre errata 388 Bug #40102) and not from the UMC AppCenter module.
