Convert Svn to Hg: svn.core.SubversionException: 180001 - Unable to connect to a repository at URL 'file:///var/lib/svn/trunk/ascii2psql'

[Ambarish Sridharanarayanan]

I'm trying to convert my local Subversion repository over to Mercurial. I'm a basic Svn user and a novice Hg user. I'm trying this on Fedora 17, running:

* subversion-1.7.7-1.fc17.i686
* mercurial-2.2.3-1.fc17.i686
* python-2.7.3-7.2.fc17.i686

Please see transcript below. svn list works fine. Trying to convert the repo to hg gives me an error and also seems to leave behind some stale locks, as logged by a subsequent BerkeleyDB command. Thanks for any help!

$ svn ls file:///var/lib/svn/trunk/ascii2psql
ascii2psql.pm
client.pl
convert.pl
db_dumpindices.pl
newindex.pl
post-database-TODO
reinit
rename.pl
sample-queries.sql
schema.sql
song-unicode.pl

$ hg convert file:///var/lib/svn/trunk/ascii2psql
assuming destination ascii2psql-hg
