Matthew Wild wrote: Sounds like you copied it while liferea was running? Matthew Many thanks for giving this your time and attention. I tried to be careful to stop liferea. Before I copied it, I did a CTRL+q to shut down liferea; and checked with ps aux | grep liferea, which didn't show anything. But, ever hopeful, I've just tried again immediately after a system shutdown and restart. I checked no liferea process was running, moved the profile to the NAS, and simlinked to it from my /home directory.

Thanks, Robert, that explains a lot. I now understand why some long and arcane scripts I saw for syncing Liferea had a lot of SQLite stuff in them. But the killer appears to be the problems with the buggy handling of locking on networks. I'm going to abandon this project. But I've again been very impressed with the generosity shown by folk on this list in spending time and effort suggesting solutions and helping to get to the bottom of an issue.

All you've done is to miss off the 'r' option that recurses into sub folders. The permission one is easy to fix too. All the files/folders would have belonged to you! So a quick chown command (with the recursive option) will straighten it all out once the rsync has finished...

I don't yet know what's causing the problem with the handling of these... It seems I was nearly right about the critical files, as indicated in the script here (a script for a situation more complex than mine, involving backing up with ssh): http://www.rolfs.no/2008/03/26/sync-lifereash-syncing-script/#more-99 where the essential files are indicated in these lines # Using rsync to preserve when file was last changed.. rsync -vaz -e ssh $REMOTE:$REMOTEDIR/feedlist.opml $BACKUPDIR/remote/ rsync -vaz -e ssh $REMOTE:$REMOTEDIR/liferea.db-journal $BACKUPDIR/remote/ rsync -vaz -e ssh $REMOTE:$REMOTEDIR/liferea.db $BACKUPDIR/remote/ rsync -vaz -e ssh $REMOTE:$REMOTEDIR/feedlist.opml.backup $BACKUPDIR/remote/ and much of the rest of the script seems to be about ensuring that these are the finalised and only files transferred and used (by making sure no copies of Liferea are running). The time stamps matter (of course - these are 'live' feeds); and that may be the problems with transferring the files via FAT32 - does the time stamp info disappear altogether, and cause a problem for the 'receiving' copy of Liferea?

[ubuntu-uk] How to sync Liferea on two PCs
I have Liferea installed on a laptop and a desktop (both connected to my home LAN). Currently, I have the same feeds on both. When reading on one machine, I just click past material I think I've already read on the other. But this is getting tiresome now that I have a lot of feeds, and I'd like to be able to sync the two copies of Liferea, so that I see a single version whichever machine I happen to be using. Sadly, extensive searching on the internet suggests that setting this up is tricky and messy. Any of you clever folks found an idiot-proof way of doing this?

Re: [ubuntu-uk] How to sync Liferea on two PCs
Mac, To sync my feeds up between my main laptop, Ubuntu-vmware image on my Windows work-supplied laptop and the desktop in my home office (aka back of garage! :)) I just rsync my liferea profile to my home/backup server. I have alias's set so I can 'put' and 'get' as required. Although a bit manual, it means I can both backup my feeds/articles and push/pull them to which ever machine I'm using at the time. Below is the alias's from my .bash_alias if it helps: alias lifeget='/usr/bin/rsync -avz --delete --force -e ssh [EMAIL PROTECTED]:/mnt/backup/stuart/LifereaProfile/ /home/stuart/.liferea_1.4' alias lifeput='/usr/bin/rsync -avz --delete --force -e ssh /home/stuart/.liferea_1.4/ [EMAIL PROTECTED]:/mnt/backup/stuart/LifereaProfile' I do basically the same for my thunderbird and firefox profiles also, but as well as having aliases for these, I have a bash file which has a minimal amount of checking in it, to try and avoid writing the wrong way!
