Problem Description: I’m encountering difficulties when attempting to bootstrap a Juju controller on my Ubuntu 22.10 system. Despite following recommended procedures and investing significant time into troubleshooting, I’m consistently facing errors during the bootstrap process. The primary issues appear to be related to LXD configuration and potential networking anomalies. These obstacles are preventing me from successfully establishing the Juju controller.
Log Summary:
- Bootstrap.log:
- The bootstrap process starts successfully.
- An error related to KVM support missing is encountered during the process.
- The error message mentions that KVM support is not available due to the absence of the
/dev/kvmdevice.
- LXD.log:
- A warning message appears regarding the absence of the CGroup network priority controller.
- Another warning indicates that the instance type (virtual machine) is not operational due to missing KVM support.
Symptoms:
- Bootstrap process consistently results in errors related to repository retrieval and package installation.
- LXD network retrieval occasionally produces warnings about failing to locate containers with the designated prefix.
- Log entries report issues such as “Couldn’t find the CGroup network priority controller.”
- Although the LXD setup seems correct, instances cannot be consistently retrieved from LXD.
Configuration Details:
- Ubuntu version: 22.10
- Juju version: 3.1.5
- LXD version:5.15
- Repository Configuration: Modified
/etc/apt/sources.listto point to old-releases.ubuntu.com repositories for Ubuntu 22.10. - LXD Configuration: Successfully executed
lxc init,lxc network create, and confirmed correct LXD group settings. - System Resources: Available storage and memory resources meet requirements.
Troubleshooting Steps Taken:
- Confirmed repository configuration using
apt updateto fetch package information. - Verified LXD setup through
lxd initandlxc network listcommands. - Verified network configuration and firewall status using
ufw status. - Checked for LXD logs and system logs, analyzing
bootstrap.log,lxd.log, and relevant log entries.
Logs and Outputs:
- Output from
lxc listandlxc infocommands to display instance and storage details. - Relevant excerpts from log files, such as
bootstrap.logandlxd.log, highlighting errors and warnings encountered during the bootstrap process.
Request for Assistance: I’m reaching out to the community for insights and guidance to pinpoint the underlying causes of these issues and determine appropriate solutions. Any input, suggestions, or shared experiences from fellow Juju users would be greatly appreciated.
Additional Information:
- Despite investing over 5 hours into troubleshooting, I have yet to resolve the problem.
- I have consulted official documentation, online forums, and relevant resources extensively, but the issue persists.
