I got the following error message but it doesn’t look helpful.

```julia
(@v1.5) pkg> add TikzPictures@v3.3.0
  Resolving package versions...

Ah, it seems the pkg server in China does not update for some days. The General registries are too old!

Would you mind share the result of your `versioninfo()`?

There is some updating issue in the SJTUG mirror site, if you’re directly communicate with this server, then you’d hit this issue. But generally, I failed to observe any sync delay as severe as this in the Chinese community.

```julia
julia> versioninfo()
Julia Version 1.5.0
Commit 96786e22cc (2020-08-01 23:44 UTC)
Platform Info:
  OS: macOS (x86_64-apple-darwin18.7.0)
  CPU: Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-9.0.1 (ORCJIT, skylake)
Environment:
  JULIA_PKG_SERVER = pkg.julialang.org

```

Since then, I have exported HTTP\_PROXY which faciliates downloading from github and everything seems fine.

FYI, there are BFSU and TUNA mirror sites that are well functioning
