[rdiff-backup-users] Version difference problem

[feffer]

Hi Andrew,
Here's the whole story -- hope this helps. 
btw, I really like rdiff-backup, great work, and thanks for your explanation
thx, feffer

On the server:
slug:/home/bak# dpkg -l rdiff-backup
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed
|/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad)
||/ Name            Version         Description

ii  rdiff-backup    1.1.14-1~bpo40+ remote incremental backup

On the Workstation
address@hidden:~$ dpkg -l rdiff-backup
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend

hi  rdiff-backup    1.1.16-2        remote incremental backup

This setup works even though dpkg shows rdiff is only "half-installed" on the 
ws. I get some errors in the backup log:
# July 22-2, 2008
UpdateError .kde/share/apps/knemo/statistics_eth1 Updated mirror temp file 
/home/bak/srp_hm/.kde/share/apps/knemo/rdiff-backup.tmp.25 does not match source
SpecialFileError .kde4/share/apps/nepomuk/socket Socket error: AF_UNIX path too 
long

The backup script uses "--exclude-sockets" but I get the error anyway. I'm not 
sure if this is important or related.

A test backup with this setup yields:
        slug:/home/bak$ rdiff-backup sidux-bak::/tmp test-55
        Warning: Local version 1.1.14 does not match remote version 1.1.16.
The actual backup works fine.
******************************
OK, now taking the hold off rdiff on the ws and upgrading to 1.1.17:
        hmmm, just taking the hold off dpkg now shows 1.1.16 as "fully 
installed"
        Maybe I'm OK holding it after all....

Anyway to give you the error message, now installing 1.1.17:

address@hidden:~/.ssh# apt-get install rdiff-backup

## OK, so after installing 1.1.17 on the ws, the backup was retried and got:

## As mentioned earlier, I'm OK going back to 1.1.16
## Hope this helps your development
