SSL certificate problem - can't get local issuer certificate #2576

Open tahzabbani opened 3 years ago

tahzabbani commented 3 years ago

Describe the issue

After downloading MSYS2 I try to run the initial pacman -Syu and pacman -Su commands each file fails due to the SSL certificate problem.

The output of pacman -Su is as shown:

:: Starting core system upgrade...
 there is nothing to do
:: Starting full system upgrade...

I have tried to use the command pacman -S ca-certificates but it also failed for the same problems. Is it possible to ignore the SSL verification?

hi, i got the same problem, so i tried the below step, maybe you don't need the 1st step

  1. add the proxy 
    export http_proxy=<proxyip>:<port>
export https_proxy=<proxyip>:<port>
  2. \msys64\etc\pacman.d, edit all the below mirrorlist.*, add your favorite mirror like the fastest in your country, and add it in the first row, also remember changing the "https" to "http", like below: 
    
# See https://www.msys2.org/dev/mirrors

Server = http://mirrors.tuna.tsinghua.edu.cn/msys2/mingw/clang32/ Server = http://mirrors.ustc.edu.cn/msys2/mingw/clang32/


for above 2 steps, i can download all the packages in my companry, hoping can help you

I'm still unconvinced if this was my problem—since a direct inspection of the certificate chain with openssl s_client didn't show any of my company's man-in-the-middle certs—but this workaround does seem to have worked for me.
