Hi all

I run
hg pull  g...@github.com:mathworks/Emacs-MATLAB-Mode.git

And obtain
Warning: Permanently added 'github.com' (ED25519) to the list of known hosts.
importing 30 git commits
abort: 00manifest@f5e8f9a6cd4de062f73daf367488a95cda00b5bc: no node
warning: changegroup.diffstat hook exited with status 255
new changesets 955972753730:f4847dcc61b7
(run 'hg update' to get a working copy)

So I am asking: how serious is this error?

Regards
