Linear Regression not working due to wrong kind of array

I try to deal with my homework. The Job is to take this Data and perform a linear regression on it.

The code is published here.

I am quite new to programming in Python and in data science. So I tried transforming as the interpreter suggests, but it didn’t work.
My first error was that there was a 2d array expected but 1d given. Then I took the pure array and put it into an empty one suggested by a StackOverflow answer now the error is that a scalar array is given but a 2d array is given.

import pandas as pd
from sklearn.preprocessing import StandardScaler

#Import
data = pd.read_csv('uscrime.txt', sep="t")
crime = pd.concat([data], axis = 1)
print(crime)

from sklearn.linear_model import LinearRegression
regression = LinearRegression()
from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(crime.get("M"), crime.get("Crime"), test_size=0.2, random_state=0)

X_train_new = []
X_train_new.append(X_train.values)

y_train_new = []
y_train_new.append(y_train.values)

regression.fit(X_train_new, y_train_new)

import pandas as pd
import numpy as np
from sklearn.preprocessing import StandardScaler
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split


data = pd.read_csv("http://www.statsci.org/data/general/uscrime.txt", sep="t")
x = data.loc[:, data.columns != 'Crime'].to_numpy() 
y = np.squeeze(data.loc[:,'Crime'].to_numpy())

regression = LinearRegression()

regression.fit(x, y)
