Description Kjell Irgens 2021-04-24 06:32:48 UTC
Description of problem:

gem2rpm uses a previously deprecated uri-open api that has been removed from Ruby 3.0.

Version-Release number of selected component (if applicable):

rubygem-gem2rpm-1.0.1-7.fc34.noarch

How reproducible:

Always

Steps to Reproduce:
1. 

Run:

gem2rpm  --fetch something

"something" is non-existing gem, but it always fails when using --fetch

Actual results:

/usr/share/gems/gems/gem2rpm-1.0.1/bin/gem2rpm:55:in `initialize': No such file or directory @ rb_sysopen - https://rubygems.org/api/v1/gems/something.json (Errno::ENOENT)
	from /usr/share/gems/gems/gem2rpm-1.0.1/bin/gem2rpm:55:in `open'
	from /usr/share/gems/gems/gem2rpm-1.0.1/bin/gem2rpm:55:in `<top (required)>'
	from /usr/bin/gem2rpm:23:in `load'
	from /usr/bin/gem2rpm:23:in `<main>'

Expected results:

Gem fetch failed with error: 404 Not Found
