CUPS Cloud Print February Release – Better Logging, stability enhancements

calendar Feb 10, 2014 · cloud cups google cloud print Linux printing

This month’s release of CUPS Cloud Print is currently rolling out to the repositories, and brings a new round of bugfixes.

Most of the changes this month are related to logging output ( and fixing the annoying long standing ‘No handlers could be found for logger’ message ), and better maintenance of the file-system when packages are upgraded ( correct permissions on the config file, and managing the *.pyc files better through the package managers ).

Some Arch Linux users may also receive this error on upgrade:

cupscloudprint: /usr/share/cloudprint-cups/auth.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/cloudprintrequestor.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/__init__.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/anyjson.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/client.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/clientsecrets.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/crypt.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/locked_file.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/oauth2client/multistore_file.pyc exists in filesystem
cupscloudprint: /usr/share/cloudprint-cups/printer.pyc exists in filesystem
Errors occurred, no packages were upgraded.

The simple fix is to simply run this command as root, to remove the orphaned files, then re-run the upgrade of your system:

find /usr/share/cloudprint-cups/ -type f -iname '*.pyc' -delete
