Possible permissions error with drush make

Question

I am trying to run drush make distro.make but getting the following error. The only thing I can see I did different was ran sudo drush make distro.make once. Any ideas?

copy(/http---updates.drupal.org-release-history-drupal-7.x): failed to open stream: Permission denied drush.inc:840 [warning]

Could not download project status information from http://updates.drupal.org/release-history/drupal/7.x [error]

Non-existent project type on project drupal

previously I was running without sudo and it was working fine.

Answer 1

Problem was that running sudo drush had probably added some unwanted permissions to the cache folder. Deleting the folder solved the problem.
