In Launching ToolsForProductivity, Part 3, I described the workflow I set up to blog about ToolsForProductivity. In this post, I would like to recall some of the challenges I faced earlier with the ruby installation on Ubuntu 20.04. I will also describe the solutions I adopted to resolve them.

List of Challenges

These are the challenges I faced while performing a clean install of ruby on Ubuntu 20.04.

Uninstall RVM Completely

Since I had rvm installed already, I uninstalled it using the suggestion here,

rvm implode
gem uninstall rvm
rm -rf ~/.rvm
rm -rf ~/.rvmrc

The above commands only removed the rvm software and not its configuration or settings.

Clear RVM Configuration

Environment variables configured as part of rvm installation continue to persist

$ env | grep rvm | wc -l
5
rvm_prefix=...
rvm_version=1.29.12 (latest)
rvm_bin_path=...
PATH=/home....................
...........................rvm/bin:/home
rvm_path=/home/..../.rvm

We need to remove these settings completely1 to ensure new installations work correctly. A reference online with similar issues2 was helpful but did not solve my issue completely. Later, I found that variables were being set in multiple files (such as bash_profile) by using the strace command3.

$ env | grep rvm | wc -l
0

Modifying the source files help eliminate the issue as shown above.

Resolve the OpenSSL Lib Issue

The openSSL library was a bit challenging to install for me on Ubuntu 20.04.

After reading many suggestions on the internet, this was what fixed the issue for me.

  • First, remove existing libssl versions
	$ sudo apt-get remove libssl1.1
	$ sudo apt-get remove libssl1.0.0
	$ sudo apt-get remove libssl1.0-dev

With the above commands all ssl versions software is completely removed. The idea with the commands below is to use v1.0.0 of libssl which works as expected. I guess the older version is a bit more robust and works better, at least for Ubuntu 20.04.

	$ sudo apt install --reinstall libssl1.0.0
	$ sudo apt install --reinstall libssl1.0-dev
  • Check for the installed versions
	$ sudo apt policy libssl1.0-dev
	libssl1.0-dev:
		Installed: 1.0.2n-1ubuntu5.13
		Candidate: 1.0.2n-1ubuntu5.13
		Version table: .....
That's it !

Continue with installation of ruby

	$ rbenv install 3.2.2
	To follow progress, use 'tail -f ...
	Downloading ruby-3.2.2.tar.gz...
	-> https://cache.ruby-lang.org/pub/ruby/3.2/ruby-3.2.2.tar.gz
	Installing ruby-3.2.2...
	.....

We should now be done with the installation with installing bundler below!

$ gem install bundler

Issue with running Jekyll

Finally, if you get an issue with running jekyll itself (as below)

$ bundle install
$ jekyll -version
/usr/bin/env: 'ruby2.7': Permission denied

Then, first uninstall all jekyll versions

$ gem uninstall jekyll

Select gem to uninstall:
1. jekyll-4.2.1
2. jekyll-4.3.1
3. jekyll-4.3.2
4. All versions
> 4

Now, run jekyll using bundle (after $bundle install)

$ bundle exec jekyll serve

Conclusion

We had a look at some issues that I faced while doing a clean install of ruby as discussed in Part 3 of Launching Tools For Productivity. The steps to upgrade on Ubuntu 22.04 was straightforward with above in place. In case you have similar issues, I hope the above helps resolve them.
