The open subscheme $U$ is the smooth locus of the cone, let $F$ be the line bundle on $U$ corresponds to the divisor of a straight line through the origin. If there were a perfect complex $\mathcal{P}$ on $X$ such that its restriction to $U$ is isomorphic to $F$, then it implies that $F$ is the restriction of a line bundle on $X$, namely $det(\mathcal{P})$. But this is not the case, $F$ cannot be extended to a line bundle on $X$ | |
