pure SSH protocol connection failed: Unable to negotiate version with remote side (unable to read capabilities): EOF

I have tried various solutions like verifing ssh keys etc for last 1 week but no luck :( I am trying to push and mirror also both are failing for same reason below.

Executed: GIT_TRACE=1 git push --mirror origin

Hey,

I think part of your problem is this: git-lfs-transfer /lfs/blobs.git upload. Unless you have an /lfs/blobs.git path on your remote server, that's going to cause pushes to fail.

There's a patch that improves the error message for the trace output in the main branch, but it hasn't been released yet.

[gstjee]

but i tried on another fresh created repo and fresh push also(not any older commits or files) and it is working fine even though remote doesn't have /lfs/blobs.git .

only issue is coming on forked repos with lfs objects. if i try to push local to existing same remote forked repo or if i push/mirror local to new remote then errors comes.

[bk2204]

Are you trying to push these LFS objects to GitHub, or to a different server? It looks like your Git remote is GitHub, but I don't see the remote for your LFS remote. Can you include the output of git lfs env as a code block so we can see where things are supposed to be going?

hi earlier i redacted some account related info from first comment. anyway now including info without any changes:

• For make sure we are on same page: i have tried two things push and mirror as well for sending to fresh remote vendor.git or to same forked repo. all four scenario are giving same issue. As this is my first encounter with lfs repos so could lacks some details in describing issue.

remote repo(both fresh new & same repo): https://github.com/gstjee/vendor https://github.com/gstjee/proprietary_vendor_motorola_dubai/tree/lineage-21

Can you please include the output of git config -l --show-origin as a code block as well? From what I see, I don't see a reason that you should be attempting to use SSH from this output, since the output looks like it should be using HTTPS instead.
