The “shared stack” on lsst-dev has been refreshed to incorporate changes to the underlying Conda environment captured on various tickets (RFC-693, DM-24746, DM-24758, DM-24907). In addition, this updated version is stricter about only allowing Conda to install packages from the
conda-forge channel, which should make dependency management in cloned environments simpler.
The new stack can be found at
/software/lsstsw/stack_20200515. It currently provides weekly
w_2020_19 and later of lsst_distrib and
w_2020_20 and later of lsst_sims. It will be updated with new weeklies as they become available.
/software/lsstsw/stack/ will always be symlink to the latest shared stack.
Refer to the Developer Guide for further details.
