Cloning a project clones the subrepo from the wrong remote path

[Cathryn Griffiths]

Hi all,

I'm having trouble cloning one of my mercurial project repos that has a 
subrepo whose remote path has changed during the course of the project. 
I was hoping the community could provide some guidance on either how to 
fix this and/or why this is happening.

Here's the situation:

My project has a subrepo whose remote path has changed (Original path 
[Version 1]: git at bitbucket.org:<subrepoversion1>; New path [Version 2]: 
ssh://hg@bitbucket.org/<subrepoversion2>). I changed the path in the 
.hgsub file from that of Version 1 to that of Version 2. The .hgsubstate 
file was also updated to include the latest commit from Version 2.

When I clone my project, the subrepo that gets cloned is that of Version 
1, not Version 2. The cloning process then tries to checkout the commit 
that's provided in the .hgsubstate file. Since that commit belongs to 
subrepo Version 2, the clone aborts and shows an error message that 
"revision f3c8dab575b2d97eade69b06da1fcc2a06ba40eb does not exist in 
subrepo deps/ff-libs". Here's the output from the clone:

Here's the .hgsub file contents:

deps/ff-libs = ssh://hg@bitbucket.org/<subrepoversion2>


... and the .hgsubstate file contents:

f3c8dab575b2d97eade69b06da1fcc2a06ba40eb deps/ff-libs


Why is the cloning process pulling subrepo Version 1 and not subrepo 
Version 2?

In case it's relevant, I'm using Mercurial version 3.7.3 on Ubuntu 16.04.

Thanks!
