Git pull - smudge filter lfs failed

In my case the SSH-authenticated repository was updated to use LFS from another client and on my side Git-LFS didn't know about the SSH remote-url. What I did to fix it was the following:

Copy the URL configured in remote.origin.url (push URL for origin) to lfs.url (the URL LFS uses):

$ git config lfs.url $(git config remote.origin.url)

(If your remote is not named origin then change to your remote name.)

Then run

$ git config lfs.url

to show the URL and confirm that it does indeed contain an SSH url, and not some HTTP/HTTPS url.

Then you can

$ git pull

Done.

If you screwed up before and master and orgin/master have somehow diverged as was the case for me then you might need to git checkout -fB master origin/master (this doesn't ask and overwrites the local version of the master branch, so beware and execute carefully!).

In my case, I have to add one more step after following the instructions provided by the answer by @grandchild. As explained by @grandchild, my remote git repo was changed to use protocol ssh from original https recently. In my git configuration, git configuration "http.sslverify" was not set originally. I believe the default value is true if it is missing. It caused the error "smudge filter lfs failed". Once I set it to false

$ git config http.sslverify false

It works without errors.
