I am using the TexLive 2020 distribution, running on Ubuntu 20.04.2 via Windows Subsystem for Linux 1 (WSL1) on Windows 10, if that matters. I just noticed that the package siunitx has had a major update and I would like to try it out. I saw this post and I tried running the command tlmgr install --reinstall siunitx. I have to do it using sudo and when I do it times out and says the following in the terminal.
/usr/local/texlive/2020/bin/x86_64-linux/tlmgr: TLPDB::from_file could not initialize from: http://mirror.utexas.edu/ctan/systems/texlive/tlnet/tlpkg/texlive.tlpdb
/usr/local/texlive/2020/bin/x86_64-linux/tlmgr: Maybe the repository setting should be changed.
/usr/local/texlive/2020/bin/x86_64-linux/tlmgr: More info: https://tug.org/texlive/acquire.html
I also tried changing the mirror from the utexas one to https://ctan.math.illinois.edu/ but I get a similar error.

Does anyone know what the problem might be? Or how I could fix it?
