I'm getting errors in apt commands also: 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Output of ls -l /usr/bin/python3: ls: cannot access '/usr/bin/python3': No such file or directory I got this error Cannot import name '_gi' from 'gi'(/usr/lib/python3/dist-packages/gi/_init_.py) I opened Xterm and typed 'gnome-terminal'. Using the command sudo apt-get remove gnome-terminal & sudo apt-get install gnome-terminalīut it is not opening. Where /opt/openssl is the home directory and /opt/openssl/ssl is the directory where OpenSSL will store certificates and private keys.I upgraded my python to 3.7.1 from 3.6 since then I am not able to open my GNOME terminal. config -prefix=/opt/openssl -openssldir=/opt/openssl/ssl Should you need, these applications are in Ubuntu repositories and can be installed via APT.Įxtract the downloaded zip file into this directory: $ sudo tar xfzv ~/Downloads/openssl-1.1.1g.tar.gz -directory /opt/opensslĮxecute the following command to create the Makefile: $ sudo. In an Ubuntu 20.04 or 18.04 desktop these tools come installed by default: $ perl -version To do that we need to create and change directory by typing: $ sudo mkdir /opt/opensslīefore proceeding verify if Perl, GCC and Make are properly installed by checking their versions. We will install the new version at /opt/openssl. Created a symbolic link to /etc/ssl/certs, enabling using default trusted certificate authorities.Directory entry /usr/bin/openssl became a symbolic link to /opt/openssl/bin/openssl and.Ubuntu 18.04 doesn’t recognize the environment variable LD_LIBRARY_PATH, using ldconfig instead.

The procedure that follows is based on the one posted at Ubuntu’s community knowledge base “Ask Ubuntu” and can be found here. Using Google’s Chrome Security tab within the Developer tools, one can validate that the issuer “ Let’s Encrypt Authority X3” (trusted by the browser) issued the certificate to the domain meaning that this is a Domain Validation certificate, enabling anyone to trust the signatures downloaded. To trust these signatures it is good practice to verify the certificate of the domain (bellow figure). The next step thus is to download the required keys (one in levitte.txt and the other in caswell.txt) and import them into GnuPG database. Current members that sign releases include Richard Levitte and Matt Caswell.” Following the link at OMC page we reach the members’ public keys. Step 3: Check downloaded zip file signatureīefore installing the content of the downloaded zip file we will verify its signature, using GnuPG shipped with Ubuntu (this can be trusted as mentioned at GnuPG).Īt OpenSSL download page we find the following information : “PGP keys for the signatures are available from the OMC page. In the image below the above commands are underlined in yellow and the checksum result (OK in this case) is underlined in green: Step 2: Check for corruption comparing SHA256 check sum form here with computed check sum of the downloaded zip file: $ wget Step 1: Download openssl-1.1.1g from here and save it into ~/Downloads directory: $ cd ~/Downloads In my case “OpenSSL 1.1.1 ” was the result. The first thing to do is to check what version is installed: $ openssl version

While I cannot see any reason this procedure should not work on Ubuntu 16.04 (if you do please let me know), it was not tested. I assume the reader is familiar with bash commands and, of course, the update will be on a Ubuntu 20.04 or 18.04 box. In this story I will guide the reader on how to proceed with this update without breaking any interoperability with existing applications that depends on OpenSSL. At this moment OpenSSL 1.1.1 series’ latest version is ‘1.1.1g’ shipped on Aug 6th. Ubuntu 20.04.1 (the latest 20.04 update as of September 2020) comes with “OpenSSL 1.1.1 ” installed and Ubuntu 18.04.03 (the latest 18.04 update as of August 2019) comes with “OpenSSL 1.1.1 ” shipped. This is specially true not only due to the role it plays in issuing certificates, but also after the lessons learned with Heartbleed. If you use SSL/TLS protocol in your application, or you are about to doing it, recommendation is to keep OpenSSL updated. While these changes are reflected in the commands, the pictures illustrating the results of these commands remain unaltered. changing the letter ‘c’ in the original version to the letter ‘g’ in the commands of the updated one. Basically the only thing I changed in this story was the letter that references OpenSSL 1.1.1 series, i.e. Since then Ubuntu 20.04 was released and OpenSSL newest version was published on August 6th 2020. A year has passed since I published this story.
