# Troubleshooting
In case you get similar errors:
>while setting up the build environment: executing '/nix/store/hg1plgwh2439jr117s5648fmgrvyc4kn-bootstrap-tools/bin/bash': Exec format error
look more further up the error log if there is:
>ED25519 host key for [localhost]:2222 has changed and you have requested strict checking.
Host key verification failed.
If so disable it either via `-o UserKnownHostsFile=/dev/null` and accepting the changed key or by adding `StrictHostKeyChecking no` to the host entry in `/~.ssh/config`. Probably you need to remove old host entries from the `~/.ssh/known_hosts `as well.
