T stopped working after latest updates on Ubuntu/AWS

[mikkokotila]

I'm getting the below error message from an Ubuntu / AWS instance (where T used to work just fine). I can run "sudo t authorize" but no other command works.

/usr/lib/ruby/1.9.1/psych.rb:203:in parse': (/home/ubuntu/.trc): could not find expected ':' while scanning a simple key at line 63 column 1 (Psych::SyntaxError) from /usr/lib/ruby/1.9.1/psych.rb:203:inparse_stream'

What Ruby version are you using?

[mikkokotila]

ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

With the same version T works fine on another AWS instance.

Thanks for quick response.

[sferik]

Did you copy your ~/.trc files onto those new instances? Is it possible those files were corrupted?

What is the output of the following command?

ruby -e 'require "yaml"; puts YAML.load_file("#{ENV.fetch(:HOME.to_s)}/.trc").to_yaml' | head -1

I get the output:

re ~/.trc

I checked and none of the systems, 2 that are still working fine and 2 where t is not working have nothing in ~/.trc.

Also small clarification is that I've run t on the 2 instances that are not working now just fine for 6 months.

I don’t think it’s possible that it’s “working just fine” on a system without a .trc file. It might not be stored in your home directory but it’s gotta be somewhere.

Sorry my bad, I was looking for a folder with files in it. I do have ~/.trc and you were correct, the file is for some reason corrupted. It looks perfectly fine, but there is one newline and 'p' on the resulting new row. Once the 'p' is removed together with the newline, it works fine. In the other system the .trc file is completely empty. Will fix it later and report back. Thanks a lot, and sorry for the extra step in troubleshooting this.
