[FAIL] Host key verification failed: Pumanew

Hi,
The UM suite u-cq224 which has been running smoothly when submitted earlier from pumatest is giving the following error while I try submitting the job now from pumanew. This is the first time I am attempting a UM suite submission after the migration to the pumanew.

best regards,

have you added your archerum key to the agent? (ssh-add ~/.ssh/id_rsa_archerum)

make sure you can run:
ssh tfrancis@login.archer2.ac.uk ls
and see the files on your /home drive on archer2. You should be able to do this without being queried for yes/no confirmation or giving a password

You can delete the offending lines of known_hosts (probably fine to delete the whole file)

I’m not sure if you need a new key - if so you may need to wait until Monday as it’s a strike day. You may be able to get by by deleting the known_hosts though, so give that a go.

Also - you may have to type ‘yes’ once - but as long as it goes through the 2nd time you should be fine
