GPG verification - don't work


I try to verify litecoin wallet by pgp.
When i try get pgp key from:
gpg --keyserver --recv-key FE3348877809386C
i have error:
gpg: keyserver receive failed: No keyserver available

but in internet i found this key on ubuntu server:
“gpg --keyserver keyserver.ubuntu. com --recv-key FE3348877809386C”

can i use this ? is not any scam ?
