Don't know whether one could get it to work with more of sid, but what I did was within squeeze only at first. After it was working, I upgraded calibre to the sid version without harm.

Another fresh setup another failure. I enabled squeeze and followed the same steps. Still get libpulse0 error. I wonder if I need to disable lenny and try only with squeeze enabled?

Failed again (libpulse0) when only and only squeeze repos active. You must have a trick by-passing this issue.

I was able to get it working at my 300th post. After doing an extra apt-get install libpulse0 while squeeze repo is still active. Calibre gets up, but seems a bit slow running. It would be great if another custom image compo is shared with the most requested apps on it.

I've succesfully install calibre with your instruction in easy debian and it worked just great until I've tried to convert a pdf to another format and have the same error over and over again any idea how to solve
thanks
this is what i get

pdftohtml is in the package poppler-utils. Install it and try again!

I tried installing calibre in EasyDebian using the install method on the calibre website. (Not from the repos.) It started downloading but stopped at 12 per cent with the following error messages:

Traceback (most recent call last):

File "/usr/lib/python2.6/urllib.py", line 271, in retrieve
tfp.write(block)
IOError: [Errno 28] No space left on device

I tried uninstalling some programs from EasyDebian to make space but then when I tried again the result was the same, it stalled at 12 per cent.

Any ideas?

Depending on the location where the temporary data is stored (either in /tmp or in the current directory) remounting /tmp or the cwd to a file or partition that has more free space might help.
