rdiff-backup exceptions.ValueError with Etch and Lenny

[danf.1979]

Hi, my production is on Etch, and I have a backup server on Lenny. I had made a backup with rdiff some days ago, and it worked. But today, I tried to make an incremental backup, and rdiff-backup died with an exceptions.ValueError :S.

From lenny I runned:


# rdiff-backup -v5 --print-statistics --exclude /tmp --exclude /mnt --exclude /media --exclude /proc --exclude /sys --exclude /dev --exclude /cdrom --exclude /floppy root@remote-server.com::/ /home/backup/remote-backup


And this is what happened:

As I said, the first time I runned the backup it finished with no errors. That was, maybe, 4 days ago. Yesterday, rdiff-backup was updated from 1.1.9-2 to 1.1.12-1 via aptitude. Today it failed.

Any help?

Well, if someone is interested on a solution for this, I downgraded the lenny package to rdiff-backup from the stable distribution.
For that, you'll have to modify /etc/apt/preferences

Package: rdiff-backup
Pin: release 1.1.5*, a=stable
Pin-Priority: 1001

Package: librsync1
Pin: release 0.9.7*, a=stable
Pin-Priority: 1001

Package: python-pylibacl
Pin: release 0.2.1*, a=stable
Pin-Priority: 1001

Package: python-pyxattr
Pin: release 0.2.1*, a=stable
Pin-Priority: 1001

Those are the packages from stable, rdiff-backup and dependencies. You'll have to modify /etc/apt/sources.list also so to load etch packages with aptitude update.
Uninstall rdiff-backup, and then install the stable version with aptitude install rdiff-backup.
Then, reverse changes on /etc/apt/sources.list, but leave /etc/apt/preferences as it is. Don't touch it.
