Unfortunately, this doesn't work. I have changed it to wontfix, and
posted the following message on the ticket:
Unfortunately, this doesn't work. Probably the .sig files depend on
the version of Magma. I tried applying your patch and got then using
it as a different user and got:
{{{
Runtime error in 'AttachSpec': Could not remove the invalid signature
file /Users/wstein/sage/data/extcode//magma/latex/latex.sig
}}}
Since there are dozens of Magma versions out there, and we can't know
which one people are using, there is literally *no possible way* to
solve this problem without the user running a command such as
{{{
sage: magma('2')
}}}
as a user with write permissions to the extcode/magma directory.
Since the error message clearly states that this is a permissions
problem, there is nothing further to do really (i.e., nothing on the
sage side). This is just the way Magma works.
