----------------------------------
Summary: [CI] Make Travis CI resilient against GPG errors
Key: ARROW-4785
URL: https://issues.apache.org/jira/browse/ARROW-4785
Project: Apache Arrow
Issue Type: Improvement
Components: Continuous Integration
Reporter: Hatem Helal
Travis Jobs sometime fail with a GPG error:
{{W: An error occurred during the signature verification. The repository is not
updated and the previous index files will be used. GPG error:
https://packagecloud.io/github/git-lfs/ubuntu trusty InRelease: The following
signatures couldn't be verified because the public key is not available:
NO_PUBKEY 6B05F25D762E3157}}{{W: Failed to fetch
https://packagecloud.io/github/git-lfs/ubuntu/dists/trusty/InRelease The
following signatures couldn't be verified because the public key is not
available: NO_PUBKEY 6B05F25D762E3157}}{{E: Failed to fetch
http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-i386/Packages.gz
Hash Sum mismatch}}{{W: Some index files failed to download. They have been
ignored, or old ones used instead.}}{{The command "if [ $TRAVIS_OS_NAME ==

It would be nice if the number of retries, timeout, or both could be increased
to make the travis jobs more resilient to this seemingly sporadic issue.
