Crash, with "%d format: a number is required, not str"

[Dominik Wujastyk]

NSsbackup crashes after a while during a backup, with the message popup box

An error occurred: '%d format: a number is required, not str'

I'm using .2, rc9 from the ppa. Current and up-to-date.

Ubuntu Linux Lucid, up to date as of today. Kernel 2.6.32-22-generic running on a Lenovo Thinkpad T500.

Thank you for reporting this issue.

Can you provide some more information how to trigger this bug?
Maybe you could post the configuration used.
Can you post the log file written during the error? If you got no log file could you try to reproduce the issue while setting the log level to 'Debug'?

Thanks.

Same here.

Last lines in log are:

Thank you so much for this additional information. Helps a lot.

Jean-Peer, the same happened to me just now, too ("TypeError: %d format: a number is required, not str"). Do you want/need the output from my nssbackup.log as well?

Another "problem" (not a real problem for me, though) is, that I wanted nssbackup to make additional backups to existing ones already made with sbackup. I get a warning which reads:

2010-05-17 21:45:30,190 - WARNING in BackupManager.makeBackup(308): There are snapshots with old snapshot format. Please upgrade them if you want to use them.

So, how to upgrade them? It's not a problem in my case to start the backups from scratch with nssbackup. I just noticed the warning and wondered how to "upgrade" existing ones. There may be other users who can't simply backup from scratch, so they may get into trouble when switching from sbackup to nssbackup. Btw, the backup did not perform due to having not enough space left on my backup stick (8 GB stick) as nssbackup wanted to start a full backup which obviously is related to the old archive format already on the stick.

Thanks, Frank

Update from me:

I just deleted the old sbackup's archives from my stick and ran nssbackup to make backups from scratch and everything worked well. No more "TypeError: %d format: a number is required, not str" for me so far. I'll keep you posted if there are any more errors in this regard when my auto-backup is done tomorrow evening.

A fix for this problem is already committed to the 0.2 series branch and will be included in the next release (the final 0.2.0 release) in short time.

The error is triggered if not enough free disk space is available for the current backup. In such cases an error message is printed, and this message is errorneous. Due to this fact, the problem vanished for you after you've deleted old backups.
