Two SlicerMorph and MorphoDepot packaged extensions for todays Stable 5.12 build

Support
1

On a clean Slicer 5.12.0 (revision 34621) Linux install, installing SlicerMorph or MorphoDepot via the Extensions Manager (installExtensionFromServer) fails with “Failed to retrieve metadata for … extension”. The other extensions install fine.

Root cause. Both extension items on slicer-packages currently hold two build files for r34621 (a stale build + the current one). The Extensions Manager fetches /api/v1/item/{id}/files and explicitly rejects any item that does not have exactly one file — see qSlicerExtensionsManagerModelPrivate::downloadExtensionByName in Base/QTCore/qSlicerExtensionsManagerModel.cxx (v5.12.0):

// GET /api/v1/item/{item_id}/files
if      (results.isEmpty())     return nullptr;      // 0 files
else if (results.count() == 1)  { file_id = ...; }   // exactly 1 -> OK
else                            return nullptr;      // >1 file -> "not expected", bail

so count()==2 → nullptr → “Failed to retrieve metadata.”

Reproduce (public read API):

BASE=https://slicer-packages.kitware.com/api/v1
APP=5f4474d0e1d8c75dfc705482      # Slicer app id

# Manager resolves the extension item for r34621:
curl -s "$BASE/app/$APP/extension?baseName=SlicerMorph&app_revision=34621&os=linux&arch=amd64&limit=1" | jq -r '.[0]._id'
#   -> 6a3c00dc3e1fb85a58476a8b

# ...then GETs its files and requires exactly one. This returns TWO:
curl -s "$BASE/item/6a3c00dc3e1fb85a58476a8b/files" | jq -r '.[] | "\(._id)  \(.name)  created=\(.created)"'
#   6a3c00dd3e1fb85a58476a92  34621-linux-amd64-SlicerMorph-gite870ab7-2026-06-17.tar.gz  created=2026-06-24T16:07:57Z   (stale)

# MorphoDepot has the same problem (item 6a3beaff3e1fb85a5847514a):
curl -s "$BASE/item/6a3beaff3e1fb85a5847514a/files" | jq -r '.[] | "\(._id)  \(.name)  created=\(.created)"'

Can someone remove the stale older file from each item so each has exactly one (count()==1):

  • SlicerMorph item 6a3c00dc3e1fb85a58476a8b → delete file 6a3c00dd3e1fb85a58476a92 (gite870ab7, 2026-06-17)
  • MorphoDepot item 6a3beaff3e1fb85a5847514a → delete file 6a3beb013e1fb85a58475152 (git5567e0d, 2026-06-24)
