问题
I am trying to install Oracle JDK 1.7 on Windows subsytem for Linux (Ubuntu 14.04) and I get the following error:
the keytool command requires a mounted proc fs (/proc).
And the installation of Java fails with tons of errors:
the keytool command requires a mounted proc fs (/proc).
dpkg: error processing package ca-certificates-java (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of openjdk-6-jre-headless:amd64:
openjdk-6-jre-headless:amd64 depends on ca-certificates-java; however:
Package ca-certificates-java is not configured yet.
dpkg: error processing package openjdk-6-jre-headless:amd64 (--configure):
dependency problems - leaving unconfigured
Setting up udev (204-5ubuntu20.19) ...
No apport report written because the error message indicates its a followup error from a previous failure.
/usr/sbin/invoke-rc.d: 1: /usr/sbin/invoke-rc.d: /sbin/runlevel: not found
* udev requires devtmpfs support, not started
...fail!
This is the full log: http://pastebin.com/gycBK1L9
I have read that maybe it is related with the chroot and the initscripts but I can't get it working.
I need JDK in order to compile Android on my machine. Any help will be hightly appreciated.
回答1:
Try this:
umount /proc
mount -t proc proc /proc
And try running apt again.
回答2:
The ubuntu subsystem in Windows is in beta/development, and as an insider you should leave the feedback (where it already exists with three upvotes as i look now) in the Feedback Hub in Windows 10 (it's an app you have installed).
It seems from what i've seen that the /proc filesystem in the ubuntu subsystem is PARTIALLY implemented, and is missing some entries.
