BuildServer fail to build at home



I follow the page and the related pages to build app in a virtual machine on my machine.
I make all step from Using the Debian provided vagrant boxes.
And after that i’ll try to build f-droid app but it failed with the following errors. I think i miss something to make the link between the jessie64 box i’ve build and the build here. How can i tell him to build using jessie64 box saved in .cache directory.

Another Question: Do you still use Jessie in production, you’ve not moving to stretch?

The above shows information about all known Vagrant environments
on this machine. This data is cached and may not be completely
up-to-date. To interact with any of the machines, you can go to
that directory and run Vagrant, or you can use the ID directly
with Vagrant commands from any directory. For example:
"vagrant destroy 1a2b3c4d"

An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and try

Couldn’t open file /home/fdroid/fdroiddata/builder/buildserver
ERROR: Could not build app org.fdroid.fdroid: could not bring up vm 'builder_default’
INFO: Build for app org.fdroid.fdroid failed:

Interesting, this is also the same error we are seeing on our staging environment:

@uniqx I’ve been meaning to ask you about that, any ideas?


@Schoumi: @hans: I need to do some debugging to get to the bottom of this. This is a nasty one to find since it only surfaces on very long build runs. So please be patient. A workaround would be to raise your users limitation on concurrently open files.

Would be nice to get some feedback on how that quick-fix worked out for you.
