I think this should fix itself when /usr/share/
Nevertheless, unity8-lxc-setup should be fixed to handle that error, I guess.

any suggestions how to fix it locally?
| Christopher Townsend (townsend) wrote : | #4 |
Sorry about this folks! I didn't realize that something like this would happen when there is no current development release. Lesson learned:)
As far as a fix, I will work on one, but for the archive version of unity8-lxc, we will have to issue an SRU and that takes a bit. The "fix" in disto-info-data will probably occur sooner than a unity8-lxc SRU.
However, I do have a development ppa (ppa:unity8-

This bug appears to be fixed now in the PPA, thanks!

unity8-lxc-setup: error: No Unity 8 Desktop Next ISO exists!
| Alex Elliott (gunwalloe) wrote : | #12 |
I am now also receiving this above error.
I have checked the cdimage.ubuntu.com files and there is no longer a vivid current iso there.
| Christopher Townsend (townsend) wrote : | #13 |
For those receiving the error of "No Unity 8 Desktop Next ISO", it's due to Unity 8 Desktop Next moving to Wily. The unity8-lxc-setup program tries to be smart on figuring out the development series by using the data provided distro-info-data. distro-info-data with support for Wily is current in the -proposed pockets of various Ubuntu releases. Either you can enable -proposed or wait until it gets promoted to -updates.
Sorry about the failures, but this is really out of my control...well I guess I could add a manual override in unity8-lxc-setup. MAybe I'll look into that.
Thanks!

so i may create a partition with wili and use it to test unity8 preview in lxc? can i use the same ppa?
| Christopher Townsend (townsend) wrote : | #15 |
Hi corrado,
No, there is no reason to have to create a Wily partition to run unity8-lxc, if you don't want to. One of the main points of unity8-lxc is to allow users to try out the latest and greatest Unity 8 desktop without having to upgrade their Ubuntu release of choice, be it Trusty, Utopic, Vivid, or Wily. It uses the Linux Container (LXC) technology to achieve this.
LXC is basically an isolated file hierarchy that resides on the host's disk that contains the files for the distribution you want. Think of it as a very advanced chroot.
I've taken great pains to try to make this work for all of the above listed Ubuntu versions, but I'm also relying on LXC which can change and break things. Also, Unity 8 and Mir are in constant development, so things can break there that are out of my control.
That all said, an updated distro-info-data should be in -updates now, so downloading the latest the Ubuntu Desktop Next ISO should be working again.
Thanks for you interest!

Since a new distro-info-data has been released, I'm turning down the severity of this bug.

This bug was fixed in the package unity8-lxc - 1.0.4+15.
---------------
unity8-lxc (1.0.4+
[ Chris Townsend ]
* Bump version to 1.0.4.
* Automount /proc to avoid a race when attaching to a container to run
a command. Also remove the ugly sleep workaround. (LP: #1428848)
* Cache a copy of upstart-sysv when downloading the Unity 8 Desktop
Next ISO image. This will keep the ISO and the upstart-sysv package
in sync. (LP: #1458236)
* Catch the exception when distro-info-data is outdated during dev
release transitions. Use the current stable release instead when the
dev release has not been updated. (LP: #1448521)
* Terminate the session instead of killing the user when logging out
of the Unity 8 LXC session. This is much less aggressive and keeps
ssh sessions alive. (LP: #1456604)
* Use upstart-sysv in the Unity8 container instead of systemd. This
fixes a slew of issues when using systemd in the container. (LP:
#1437900)

Seems to be broken again, with
"unity8-lxc-setup: error: No Unity 8 Desktop Next ISO exists!"
| Christopher Townsend (townsend) wrote : | #20 |
Yes, the ISO has been removed, so unity8-lxc-setup is broken. I'm currently working on coming up with a different way to install the Unity 8 desktop session in the LXC (tracked in bug #1477720), but systemd is giving me fits.
Status changed to 'Confirmed' because the bug affects multiple users.
