Hi Juan,

Could you provide the output of the followings:
1. start an Erlang shell in the debug mode (erl -init_debug);
2. copy and paste:


You should get something like I attached here if everything goes well.

I was using CouchDB 1.10 on Ubuntu 10.04 and was working pretty well.

Now, I've upgraded to 1.20 using sources, and now, CouchDB don't start with this error:

{"init terminating in do_boot",{{badmatch,{error,{"no such file or directory","os_mon.app"}}},[{couch,start,0},{init,start_it,1},{init,start_em,1}]}}
init terminating in do_boot ()

This error suggests that erlang-os-mon package is not installed. But, it's already installed.

I've tried to delete files in /usr/local/lib/couchdb/erlang/lib has suggested in http://wiki.apache.org/couchdb/Installing_on_Ubuntu and do 'make install' but still not working.

Version 1.10 was working perfect.

Any idea ?
