Hi,

openssl plans to release a security fix with moderate severity in a few
hours now, not sure if it must trigger a rc3 (i opened a ticket anyway:
https://trac.sagemath.org/ticket/33761).

Ciao,
Thierry

The release is postponed on Tuesday 3rd May 2022 between 1300-1700 UTC.
As it is of moderate severity, i guess we could ignore it for 9.6 if it
is ready.

Ciao,
Thierry

Hi:

On a Ubuntu 21.10 laptop, I got this:

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):
* package: giac-1.6.0.47p3.p0

The log file is attached.

This looks like incompatiblity with system-wide nauty (I assume Sage installed its own nauty, right?/

Can you uninstall the system nauty and try again?

I don't see a system-wide nauty. I installed giac 1.6.0 using
sudo apt install xcas
but
./config.status --recheck && ./config.status
make
didn't seem to pick it up.

the system wide giac might come with libnauty, no? Anyway, the following are errors from you log, and they are about 

missing symbols in a copy of libnauty.so

in /usr/lib

So you do have it there....

top-level config.log please

[François Bissey]

Actually, that means libcliquer is not installed as a dependency of nauty. Those symbols are supposed to be from libcliquer.

[Matthias Köppe]

There are some undeclared dependencies - see https://trac.sagemath.org/ticket/31403

[François Bissey]

In that particular case, because giac from the system is used, either the system giac is missing some dependencies or someone broke their system by removing libcliquer without removing nauty itself (which with apt may mean giving the wrong answer to a prompt explaining that you are about to break something).
Unless the user explicitly broke their system, I’d say it is a bug in that distribution.

Thanks Dima for this hint. (And thanks everyone else as well
for their emails.)

I tried
sudo apt remove libnauty2-dev
and
sudo apt remove xcas
then

./config.status --recheck && ./config.status
make

5 hours later, the compilation finished without errors.

This issue was that I just upgraded ubuntu to 21.10 and that
broke my older version of sage. Thanks for the help
recompiling. Everything is working fine now.

While you are at it, Ubuntu 22.04 is out! --Samuel

[Thierry Dumont]

I (re)installed Sage (9.5 and 9.6.rc2) on Ubuntu 22.04. Everything seems ok.
