Until the tarball is uploaded to our download mirrors
(which should happen soon now), some workarounds
are described the ticket description for
- Sage Trac ticket 27309: Update FriCAS to 1.3.6
One of them is:
```
$ SAGE_SPKG="sage-spkg -o" ./sage -i fricas
```
The other one is:
```
$ ./configure --enable-download-from-upstream-url ./sage -i fricas
```
Or you could manually download the tarball to your `upstream` folder
(see the upstream url in `src/build/pkgs/fricas/checksums.ini`).
Another way, suggested in a comment at ticket #29314,
where we upgrade the `gap` and `gap_packages` SPKGs,
is to use `sage -f` instead of `sage -i`. Apparently that
not only forces reinstallation if a package is already there,
but also forces downloading from upstream url if the
tarball is missing locally and on the Sage mirrors. So:
```
$ ./sage -f fricas
```
