How to stop using Anaconda's Version of OpenSSL

Question

I ran the following command:

sudo apt-get install --only-upgrade openssl

and the output was:

openssl is already the newest version (1.1.0g-2ubuntu4.1).

However, when I type openssl version -a into the terminal, the output is:

OpenSSL 1.0.2o  27 Mar 2018

OPENSSLDIR: "/home/vedantroy/anaconda3/ssl"

Furthermore, typing which openssl outputs: /home/vedantroy/anaconda3/bin/openssl.

It seems my system is using the conda installation of "openssl" instead of the one installed by apt-get. How do I force my system to use the version of "openssl" that is installed by apt-get?

Solution 1

The openssl package installs an executable file called openssl as /usr/bin/openssl (see dpkg -L openssl).

You have openssl installed as /home/vedantroy/anaconda3/bin/openssl.

The directory /home/vedantroy/anaconda3/bin occurs in $PATH before /usr/bin appears.

Your $SHELL picks the first openssl it sees.

You have several choices:

• Rearrange $PATH. However, if there are any other system binaries Anaconda wants to override, this will screw that up.
• I assume that you own the directory /home/vedantroy/anaconda3/bin, so chmod -x /home/vedantroy/anaconda3/bin/openssl;rehash will let you use /usr/bin/openssl.
• Add alias openssl="/usr/bin/openssl" to your ~/.bashrc. WIll only work for shells.

Solution 2

In your case I suggest creating an alias to apt installed version of openssl:

alias openssl='/usr/bin/openssl'

Put your alias somewhere which it gets sourced automatically like: .bashrc.

You can also run it directly:

/usr/bin/openssl

Or change the PATH environment variable, which can't be a good option in your case because you are actually using Anaconda.

Whenever you want to use Anaconda version then run one of these:

\openssl
""openssl
''openssl
'openssl'
"openssl"
command openssl

Solution 3

Conda may be active by default in your shell, often the case for an anaconda installation on Ubuntu. There may be (base) at the beginning of your shell prompt.

Simply running conda deactivate may fix the issue. It did for me.

[George Udosen]

please explain the characters before the openssl!

[Ravexina]

@GeorgeUdosen Causes aliases to be ignored and the actual comment be invoked or bash built-in if any exists (Which in this case there is no built-in so the actual command will get to run).

Your answer is unclear as to did the link fix it.
