Are you aware of 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=523368 and related 
bugreports?


Quoting the bugreport:
the solution is to set net.ipv6.bindv6only=0 in
/etc/sysctl.d/bindv6only.conf . The bug has been fixed in openjdk.

Hope it helps

Johan

Re: Bug#573538: Packaging again sagemath

2010-07-20 Thread Johan Grönqvist

Hi List,

As a normal user who has read the emails, but not taken part in the 
discussion due to lack of time for commitments, I would like to comment.

Yes, that's my interpretation too. But I think that, in order to have
good communication with upstream, we'll have to show that the package
can be maintained and won't fall forgotten as last time.



As I read the reaction from upstream, they were frustrated that people 
installed the package with the expectation that it should be current and 
just work.


As Tim stated, I think the problem was that it entered into a repository 
where people expect such things, and that this happened when it was 
released as part of a stable ubuntu release. That is, the problem was 
not primarily debian-related.


The response and proposals from upstream also seem to argue about ubuntu 
rather than debian.


IMHO and AFAIUI:

For stable debian, people probably do not expect packages to be up-to-date.
For unstable debian, people probably do not expect packages to be bug-free.
For experimental debian, people probably do not install packages without 
knowing what they are doing, and without expecting them to work without 
problems.


It was also stated (by Tim?) that due to a process involving the 
NEW-queue (I think), removing the package from debian and then 
reintroducing it again could be much more work than moving to 
experimental and working from there.



I would appreciate getting an up-to-date sage-package in debian again, 
so I hope you find time and interest enough to continue the work.


Regards

Johan

Re: Reproducibility

Usually we have some version in stable and some people will use it.

In
Debian we have the universal operating system that incorporates all
software and 'stable' is a snapshot of everything at the time of release
-- and this is not what scientists want.

That is why we have backports.org and neuro.debian.net that offer at
least the latest and greatest for 'stable'. But this is still not
enough.


This is why I like the approach of Gobolinux, at least in theory.

As I understand the basic idea of gobolinux, every packages follows a 
system like the debian alternatives system, where the alternatives are 
the different versions of that package. Upgrading therefore does not 
have to remove old versions, but can just install the new version and 
update the symlink, removing the old package can then be a separate 
procedure.


To me (IMHO) that feels like _the_ solution, when combined with the 
debian snapshot service. I imagine maintenance not to be a problem. I 
would be happy to have only the same level of support as we have now, 
but with the eternal _availability_ of all packages. Perhaps other users 
have other requirements.


Of course this also requires more form the alternatives-handling 
software in order to handle versioned dependencies when switching the 
alternatives system between different version, but I expect that to be 
doable using tools similar to those that exist now.


Regards

Johan
