[Bug 713204] Re: package backuppc 3.1.0-9ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Many thanks for pointing me back to the detail of the error report
itself.

I've run the checks it suggests (df. df -i, etc) and include for your
information a copy of the output of the terminal session showing (as far as
I can tell) that there was no essential problem beyond the fact that the
directory *cpool* had not been created. I created this directory. I then
disabled all other web servers and got Apache2 running OK.

Anyway, I then tried to reinstall BackupPC from Ubuntu Software Centre but
the exact same thing occurred - same error "Unable to make hard link...
etc".  I thought it could just be a permissions problem, so for simplicity &
speed I changed directory to /var/lib/backuppc and did a quick:

*root at jb:/var/lib/backuppc#*        chmod 777 pc cpool


After doing this, I *was* able to start the program with:

*root at jb:/var/lib/backuppc#*         /etc/init.d/backuppc start


and check into it with the web interface.... well, now, of course, I need to
re-read the documentation to find out how to locate the password to let me
in! Either that or reinstall the software and hope that with a successful
install the password will be shown on-screen... Ah well, at least with your
help I seem to have detected the main problem... permissions.

I've also had a look at the other bug report you pointed to and I conclude
that I have achieved the same outcome by a different method (i.e. I made the
directories "everyone's" rather than root's or the usual user's). My
approach is a bit of a blunt instrument and absolutely _not_ recommended for
production use! But it's fine for testing purposes.

Of course, the recent Linux Format magazine article [Issue LXF142 March
2011, page 43]  *did* suggest that BackupPC's configuration is not for the
faint-hearted :-). I only thought about using this program because it would
allow me to back up my laptop to a NAS drive; many backup programs assume
you want to backup to a physically-connected USB hard drive. So I may be as
well-off in the long run sticking with Backup-Manager - or even using mc
instead. Equally, it's no sweat to use a variant of ftp (eg ncftp does
things quite nicely) to do the job. It's just I can never resist the chance
to explore another bit of excellent free software :-)

Thanks again for your interest and advice.

John
