package brltty 5.0-2ubuntu3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Well, yes, brltty needs mountkernfs, like a lot of software actually. Having it disabled seems the culprit here, not brltty.

so how do u remove it to do the upgrade

Status changed to 'Confirmed' because the bug affects multiple users.

I think the proper solution is a versioned dependency on initscripts (of the version that provides mountkernfs)

@Charly:

Try to upgrade your initscripts package first and then upgrade the brltty package.
This worked for me

Doing apt-get dist-upgrade instead of apt-get upgrade helped in my case.

Updating the initscripts package first did indeed solve the problem for me.

I am seeing this the very first time, sorry I'm not able to add something useful. This is obviously an incomplete update from 14.04 to 14.10 and now I take the chance to upgrade to 15.04. Good luck may be with me!
