aliBuild won't init FairRoot as development package

Dear experts,
I hope my problem is not considered off-topic.

I try to initialize FairRoot as a development package when installing O2. However, the command
aliBuild init FairRoot --defaults o2
leads to the following.
Cloning into ‘./FairRoot’…
fatal: Remote branch 717dccd866ec07af10db1e021d189e9ff2ce0209 not found in upstream origin
ERROR: cannot clone FairRoot version 717dccd866ec07af10db1e021d189e9ff2ce0209
Is there any way to get this running?

Thank you very much for your support!
Thomas

I can reproduce the issue on my machine. Calling experts in (@eulisse @dberzano). If it is a bug and not something obvious, please move it to https://github.com/alisw/alidist/issues/new.

git itself seems to reject the commit:

→ git clone -b717dccd866ec07af10db1e021d189e9ff2ce0209 https://github.com/FairRootGroup/FairRoot ./FairRoot                            
Cloning into './FairRoot'...
fatal: Remote branch 717dccd866ec07af10db1e021d189e9ff2ce0209 not found in upstream origin

aliBuild init at the moment is unable to fetch a specific commit; this is a bug IMHO.

For the moment you can work it around by running:

aliBuild init FairRoot@dev --defaults o2

HTH

Thanks a lot, this does the trick.
