I came across a bizarre issue yesterday with Ubuntu WSL on my development machine.
curl: (35) OpenSSL/3.0.8: error:0A000152:SSL routines::unsafe legacy renegotiation disabled
What made it bizarre is I’d been using regular curl commands for months and seemingly overnight I began getting these errors.
It turned out that policies had been updated internally to the latest OpenSSL Versions which – if you don’t have the latest version of Curl – caused failure until the package is updated.
So – this morning – I spent some time to write up a install script to upgrade Curl to the latest version on Ubuntu.
This should work on any version of linux – just swap the apt command with yum.
git clone https://github.com/curl/curl.git cd curl sudo apt install autoconf libtool make automake -y sudo apt remove curl sudo apt purge curl autoreconf -fi ./configure --with-openssl sudo make sudo make install sudo cp /usr/local/bin/curl /usr/bin/curl sudo ldconfig
Then – to set a temporary configuration to fix the original error do the following…
echo "openssl_conf = openssl_init [openssl_init] ssl_conf = ssl_sect [ssl_sect] system_default = system_default_sect [system_default_sect] Options = UnsafeLegacyRenegotiation" > $HOME/.openssl.cnf
Under your .bash_profile for your user – add the following line…
