This tree is cloned from various linux kernel trees. Here are a sample of the error I see : $ git fsck error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index [..] error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed dangling blob fe130d58453393f15e0db82bca18f35998689a87 dangling commit 2515ddc6db8eb49a79f0fe5e67ff09ac7c81eab4 error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed dangling commit 6bb7a935489dab20802dde6c2cb7d8582f4849bf error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed dangling commit 4aba41ea8bdc1b475861f5e5c1649ab20251090c error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed [..] $ git verify-pack .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack nferre@bendor:linux-2.6-arm > git verify-pack .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack error: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack does not match index fatal: packfile .git/objects/pack/pack-2ab31ad1f8cb69d091a56fe936634e4796606d49.pack cannot be accessed What can I do to recover my git archive ?

Unlikely.

Since this is not bleeding edge, it is pretty unlikely that the corruption is due to git itself. Furthermore, the git packs are always read only once they've been created, meaning that if they weren't corrupted at some point then something outside of git caused the corruption. You really should consider the possible causes for that (dying disk, pilot error, etc). As to recovery... That really depends if you have personal work committed to your repository. If not then the easiest solution is simply to recreate it by refetching from upstream. If you have personal work in there then you could try to fetch your work branch into the newly created repository. The latest git version could help with the extraction of non-corrupted objects out of a bad pack, but if the objects you are interested in are themselves corrupted then your only hope is to have a copy of those objects somewhere else.

Nicolas, Thanks for your help. I will consider migrating to a brand new git tree with my work imported in (it seems that my local work is not affected). Just to know, as the object I try to access is not present, is there a way to rebuild the index to match this mater of fact ? Regards, -- Nicolas Ferre ```
