13346 :: Nimble error: Failed to verify the SSL certificate

• matkurianski (orginal) [2025-08-23T18:52:51+02:00] view original

  Hi folks, I just installed Nim 2.2.4 on MacOs but I keep getting this error when running nimble refresh or install:

  
   Downloading Official package list
          Tip: 3 messages have been suppressed, use --verbose to show them.
   packageinfo.nim(156)     fetchList
       
       Error:  Failed to verify the SSL certificate for https://raw.githubusercontent.com/nim-lang/packages/master/packages.json
        Hint:  Use --noSSLCheck to ignore this error.
  Run

  I couldn't find a solution yet, only saw one person having the same issue but it fixed by reinstalling, which didn't fix it for me. I have OpenSSL installed.

  I spent hours today but I still couldn't fix the issue, but if anyone is experiencing the same problem I did a workaround to at least unblock myself:

  1. I downloaded the packages.json from the official Github repo

  
  curl -k https://raw.githubusercontent.com/nim-lang/packages/master/packages.json -o ~/.nimble/packages_official.json
  Run

  2. I created pasted the following config into ~/.config/nimble/nimble.ini

  
  [PackageList] name = "official" path = "/Users/USERNAME/.nimble/packages.json"
  Run

  Now I can normally install packages, even though I didn't solve the root cause.

  Does Atlas fail with the same problem?

  Hi folks, I just installed Nim 2.2.4 on MacOs but I keep getting this error when running nimble refresh or install:

  There's some flakiness with MacOS sometimes regarding SSL certificates. I had to do something on mine recently upgrading MacOS, it was something like https://wyday.com/forum/t/5067/macos-fix-for-expired-certificate/

  Then you add in homebrew openssl and apps get really confused sometimes. :/ Probably why reinstalling (and possibly recompiling Nim) could fix it sometimes.
