Probably a copy and paste error, and you actually tried
john sha1.txt -w=password.lst

Otherwise, you should have seen the same error message as before.

This means, that your version of John the Ripper has detected the hashes
in sha1.txt as LM hashes.
Because your file is named sha1.txt, I would assume that it doesn't
contain LM hashes.
A number of different hash formats might be wrongly detected by john,
especially raw hashes using hexadecimal encoding, i.e., the hashes are
just sequences of [0-9a-f] or [0-9A-F].

I don't suggest you post one or more hashes in your sha1.txt files
(because others might be able to crack them).
But if my assumption about hex encoded hashes is right, it would be nice
to know:

Where and how did you get these hashes, which application or OS is using
these hashes?
Can you create a similar sample hash with a known trivial password, and
post both the known password and the hash here?
If not, can you at least check the length of the hash encoded string?

Is it the same length than the hex encoded string here:

echo -n "test" |sha1sum -
a94a8fe5ccb19ba61c4c0873d391e987982fbbd3  -

These are 40 characters (20 Bytes in hex encoding).
Are your hashes of the same length?
If not, what is the length?
