We have some legacy code and hence need to perform few things on ubuntu-10.04 amd64. I am trying to download a 'gperftools-2.6.90.tar.gz'. file.

wget https://github.com/gperftools/gperftools/releases/download/gperftools-2.6.90/gperftools-2.6.90.tar.gz

Error message

--2020-02-20 23:33:39--  https://github.com/gperftools/gperftools/releases/download/gperftools-2.6.90/gperftools-2.6.90.tar.gz

I also tried using curl and displayed the same error.

It appears to be a a protocol issue but not sure of fixing it / work around ?

    Dupe https://stackoverflow.com/questions/48938385/github-unable-to-access-ssl-connect-error and more. Github stopped supporting the obsolete protocols used by Ubuntu 10 (???!!!) two years ago. Download on some other system that isn't massively obsolete and then transfer to your target. – dave_thompson_085 Feb 20 '20 at 23:14
  • @dave_thompson_085 I need to compile many things and gperftools is one among them. I am actually panning to write a bash script and share the script with rest of my peers. It have tried transferring the package manually to the test bash script and it looked good. The only outstanding task is to download gperftools. – BhanuKiran Feb 21 '20 at 07:47
  • I have also tried to get it from source forge - https://sourceforge.net/projects/gperftools.mirror/ . But it has the same error. – BhanuKiran Feb 21 '20 at 07:49

    [google sourceforge TLS 1.0 support first hit](https://sourceforge.net/p/forge/site-support/17088/) says they also dropped it two years ago. Over the last few years _many_ public websites did, and many that haven't yet probably will soon. (Stack just did so a few weeks ago -- if you try to connect to SO or SX from your Ubuntu 10 that won't work either. But a bash script is also a file -- if you can transfer a bash script to the target, why can't you transfer the gperftools file? Or run your own obsolete server, or a proxy like nginx/haproxy/varnish that can do TLS1.0 down and 1.1+ up. – dave_thompson_085 Feb 23 '20 at 15:59

Ensure that your internet connection is stable and it should work fine. Also try updating your Ubuntu version to the latest one (20.04.2.0 LTS)
