if you make Sage believe that the atlas package was installed properly, |
| 30 |
the installation proceeds without trouble. So as a quick workaround, |
| 31 |
just do |
| 32 |
|
| 33 |
touch spkg/installed/atlas-<version_number> |
| 34 |
|
| 35 |
I always do this on my system. It would be good to find out the proper |
| 36 |
solution of course. :) |
