Test IIAB 6.5/master against Ubuntu 18.04 LTS daily builds

[holta]

Thanks to @floydianslips & @deldesir whose works is ongoing here:

http://cdimage.ubuntu.com/daily-live/current/ <- Josh Dennis will work on this for Jerry, to confirm that IIAB 6.5/master networking now works on Ubuntu 18.04 NON-server edition?

http://cdimage.ubuntu.com/ubuntu-server/daily/current/ <- Blondel prefers the Server Edition of Ubuntu 18.04 dailies

Related: #612 (Debian 9.3 testing)

Nodjs won't install automatically. Will give a try using manual install for Ubuntu 17.10 (Artful Aardvark).

Your distribution, identified as "Ubuntu Bionic Beaver (development branch)", is a pre-release version of Ubuntu. NodeSource does not maintain official support for Ubuntu versions until they are formally released. You can try using the manual installation instructions available at https://github.com/nodesource/distributions and use the latest supported Ubuntu version name as the distribution identifier, although this is not guaranteed to work.

FYI @deldesir's 18.04 server "daily" in question here is actually the two-week-old 2017-11-30 at http://cdimage.ubuntu.com/ubuntu-server/daily/current/bionic-server-amd64.iso (which is still the most recent posted amd64 for now, so he then upgraded with "apt update" then "apt dist-upgrade").

When running "apt -a list nodejs" he got:

nodejs/bionic 6.12.0~dfsg-2ubuntu1 amd64

He also tried https://community.parrotsec.org/viewtopic.php?id=489 without luck.

Any other tips he should try?

Editing script from https://deb.nodesource.com/setup_6.x by commenting out exit 1 in pre-release condition and adding "Ubuntu" "bionic" "Ubuntu" "xenial" in check_alt section to install it manually like If it was Ubuntu Xenial Xerus. It works.

Had to install libgl1-mesa-dev to make calibre to install. Is this #530 related?

[deldesir]

ifupdown is still mandatory at Network stage.

Looks like dhcpd service is messy. Clients won't connect to AP for me. I've already seen a similar issue that was fixed by #588. See #625 for a workaround.

Do systemctl restart iiab-cmdsrv.service when having the following error with admin-console (thanks @holta for the hint): GET-CONF FAILED and reported CMDSERV is not runnig GET-ANS FAILED and reported CMDSRV is not running.

Clarif: Admin Console (http://box/admin) was not starting for @deldesir's after every boot of his Ubuntu 18.04 Server.

Sounds like a timing issue that will have to be worked out before 18.04 is released — let us know @deldesir if you discover the root cause!

[holta]

@deldesir & @floydianslips : do you have time to create any PR's (pull requests) for the above Ubuntu 18.04 LTS issues you've resolved?

(This can also wait for IIAB 6.6 if you prefer — but if there are any late-breaking merges needed, that we should slip into IIAB 6.5 this week — let us know very soon in coming days!!)

@deldesir is there any possibility this error would go away all by itself, e.g. if you Wait A Full 5min after booting before attempting http://box/admin ? (Or have you already tried that?!)

[holta]

@floydianslips & @deldesir should I move this to IIAB 6.6?

(Or will you be submitting the 18.04 quick fixes you discovered as PR's in the coming days?)

IIAB 6.5 was supposed to have been released in November but now that we've redefined its scope into a larger 7.0-like product (*) we might need to reconsider embracing April's Ubuntu 18.04 LTS release as something to take more seriously:

https://wiki.ubuntu.com/BionicBeaver/ReleaseSchedule

(*) given IIAB 6.5's stated reason (installing IIAB over WiFi) proved Far More Complicated than anybody anticipated — this core feature remains incomplete 4+ months later — due to RPi/Raspbian WiFi bug etc, e.g. the latest being #655 where work is ongoing: "iiab-hotspot-on fails if IIAB installed via WiFi (/etc/sysconfig/dhcpd missing, so dhcpd won't start)".

[holta]

Update: With 18.04's final feature freeze rapidly approaching at the end of February, it's time now to consolidate our fixes for all "big iron" users like @m-anish, building off #502 "U17-2: refine network for Ubuntu 18.04 LTS daily builds".

IIAB 6.5 and 6.6/master now work well on Ubuntu 18.04 LTS.
