Testing IIAB on Ubuntu 24.04 LTS "Noble Numbat" pre-releases [Transmission BitTorrent service crashes on 1st browser login/visit]

[holta]

Now possible using these instructions:

• https://ubuntuforums.org/showthread.php?t=2491874
• https://launchpad.net/ubuntu/noble

Also daily builds (e.g. ISO images and cloud-installable formats, for Multipass VM's etc) will be available very shortly in coming days.

PS the OS itself is expected to be released 2024-04-25.

FYI Ubuntu 24.04 pre-release OS images are now "instantly installable" using...

multipass launch 24.04

Or if you prefer 2 CPU cores, 2GB RAM, 25G disk, and LARGE-sized IIAB auto-installed...

multipass launch 24.04 -c 2 -m 2G -d 25G --cloud-init iiab-large.yml

e.g. if you create iiab-large.yml as follows...

runcmd:
  - mkdir /etc/iiab
  - curl https://raw.githubusercontent.com/iiab/iiab/master/vars/local_vars_large.yml > /etc/iiab/local_vars.yml
  - curl iiab.io/risky.txt | bash &

A LARGE-sized IIAB install onto Ubuntu Server 24.04 is looking great so far (almost 6 months prior to OS's 2024-04-25 release of course!) Specfically, it's currently working thru Stage 8 of 9 — i.e. the usual "up-to-hourlong" compile of (BitTorrent client) Transmission 4.1.0-dev:

Not really our problem (TM!) but fyi the latest compiled-from-GitHub Transmission 4.1.0-dev is not currently reliable (perhaps in general, on all similar Linux distros?) and certainly on Ubuntu Server 24.04 here — where it's repeatedly crashing within about a minute: (though its systemd service appears to start correctly every time, for a minute-or-so anyway!)

Transmission 4.1.0-dev is not currently reliable (perhaps in general, on all similar Linux distros?)

CORRECTION/CLARIF: The first browser that logs into (IIAB's Transmission console) http://box:9091 or http://box.lan:9091 would appear to (consistently!) crash Transmission 4.1.0-dev's systemd service.

FYI 10 days later, Transmission's BitTorrent daemon (systemd service, as painstakingly compiled during MEDIUM-sized and LARGE-sized IIAB installs) still seems not to start, on some-if-not-all IIAB installs 😦

Hopefully the release of Transmission 4.1.0 (in coming months if not weeks?!) will solve this rather soon 🙏

Appears fixed with the latest (compile of) Transmission 4.1.0-dev... logging into http://box:9091 and clicking around appears to work with:
