Max,
thanks for taking the effort.
No worries.

I did my best to reproduce the issue but didn't have any luck. I
really need access to a Linux VM to debug this. So I'm praying that
Apple fixes the access restrictions to kernel extensions in their
next beta...
BTW, Metacello uses ZnClient, which uses ZnFileSystemUtils, so there
is indeed a chance that something goes wrong during download of the
zip archive and that something may be tied to a difference in the
versions of Zinc (although I still think that's unlikely).
Yes there is potential but I don‘t see it. I take a fresh 6.1 image
and load my project into. I‘m not sure but I think zinc 2.9.2 is
loaded rather early in that process. So I wonder why it does not go
wrong in the first phase. And also not if I load the test group within
the first phase.
It must be either the second Metacello invocation or the stopping,
copying and starting of the image.
I try to isolate this case more and provide a script that goes wrong
on my machine. But it will take some time because I needed to stop
trying to solve this as I wasted nearly two days on that already.
Let me know once you have something and I'll try to help out.

I checked the Parasol Archive and it does not appear to be in Zip64
format (Metacello uses ZipArchive which can't cope with Zip64 but
ZipArchive can read the Parasol zip). So my next guess is that
there's either a problem with Metacello or Pharo in the way that
ZipArchive is used (e.g. endianness problem or non-binary stream
data). It would therefore be helpful to find out what happens in
ZipArchive>>readFrom:, i.e. what kind of stream is passed / opened,
is it binary, does the file exist and is it still the correct file.
I couldn’t see anything obvious. The file in the debug message
exists, it is a readable zip file. The way Metacello uses it it is a
StandardFileStream. It switches it to binary in the code.
But the only difference between a working and non-working build is
the upgrade to zinc 2.9.2.

I'd debug it myself but I can't run VirtualBox at the moment because
I'm on the macOS beta and it won't start...

Hi Norbert,
This is a bit of a guess, but it's possible that the archive that
is downloaded from github is in Zip64 format and that the libraries
for extracting Zip64 are missing on your Linux. That would of
course contradict the experience that the same operation appears to
work in 6.1.
to be honest I don’t know what Zip64 format is. I thought the Zip
classes are pure smalltalk for unpacking.
Try extracting the archive manually on your Linux machine with the
same method that Metacello uses (I assume, Metacello uses the
ZipPlugin, which will probably use the system libraries).
I have no ZipPlugin as library in any of my vms.
But there are zips downloaded and unpacked. I start the image the
first time loading all the code of my project. Then it is saved,
copied to a new name and reopened to load the tests and then it
fails. I did try to load the tests in the first run and then it
works.
I’m running out of ideas
thanks,
Norbert
Cheers,
Max

With the help of Esteban I got one step further. If I do
MCWorkingCopy
managersForClass: ZnFileSystemUtils
do: [ :each | each ancestry initialize ]
before loading my project it updates Zinc-FileSystem as well. Sadly
it still does not work for me because I get
Loading baseline of BaselineOfMobilityMap...
...RETRY->BaselineOfParasol
...RETRY->BaselineOfParasol[31mError: can't find EOCD position
and I don’t know why. zip file is downloaded from github and
present but it fails and only on my jenkins on linux. On my Mac
this works.
I try a few things but then I’m back on pharo6.1 for the time
being :(

Really? I thought the same but then I didn’t believe it works
like that.
Anyway this would be very easy to solve. We just need to ask Sven
if he is fine with doing an empty .16 version for Zinc-FileSystem
and does an in-place version reset of 2.9.2 or a new 2.9.3. I’m
not fully convinced that will solve it but the cost won’t be
very high.

Need to investigate more. There are two .15 versions but there
is 1 year in between (if you didn’t notice TheIntegratior.15
is from 2017). Just want to have more context information
because I can only see that this is strange but lacking insight.
I’m trying to figure out why it does not update
Zinc-FileSystem. No matter what I do I cannot get Metacello to
load the newer package. That would fix the issue because I’m
loading 2.9.2 which should have Zinc-FileSystem-SVC.15 and not
stay on the one included in the image.
I think this is important for everyone that has a product based
on 6.1 and that want to migrate someday to pharo7. This way it
is impossible to do it step by step.
If there is a package .15 in the image and a package .15 in the
repo, I think Metacello will not update because it rely on the
numbers to know when to update. If it find a .15 and currently
have a .15 I think Metacello will think they are at the same
version.
