[sage-release] Re: error: Cannot perform incremental update

2016-01-14 Thread Volker Braun
After you run "make distclean & make", is lib64 a symlink? If its not then 
its a bug.

I used to have this problem too... So I didn't know how to correct it 
now I create a new git to each version and I have no more problem... 
(but that's not a way to improve correcting problems ! )

Yo,


This should if and only if you upgrade from Sage <= 7.0.beta1 to Sage >=
7.0.beta2.

It definitely happened several times.


Maybe you just switched between old and new branches?

No, the way I work with git this is not possible.

After this double "make" (the first that fails with the message above,
the second that works) it is a regular directory. If it happens again
I will post here.

If "make distclean" fails then its not going to do anything, duh. Delete 
SAGE_LOCAL by hand or "git clean -f -d -x"

'make distclean' did not fail: only 'make' failed. And I am not stuck:
the first call to 'make' fails with the error reported above, but the
second worked alright and I am now reviewing #19586 :-)

I looked through several of the threads in sage-release but couldn't 
(quickly) find anything more detailed than this.  What happened that Sage 7 
is not upgradeable?

I think that it would then make sense to have some message print out if 
someone tries sage -upgrade (if that's even still supported) lest they hose 
their Sage install, that's been a problem with such updates in the past as 
well. 

Also, can you give a little more guidance on how to still use "old" git 
branches - can we just merge in the newest Sage or will that cause problems 
as well?

Thanks,
- kcrisman
