I installed TL2021 recently. I usually issue `tlmgr update --all` after installation which worked perfectly well yesterday, but now suddenly `tlmgr` is absolutely not working. It gives me `xz: (stdin): Unexpected end of input` error. Does anyone know about this problem?

The full log for `tlmgr update --all` is as follows.
