Incus on Gentoo

Just curious if anyone has gotten Incus 0.2-r1 to work on Gentoo. I’ve get to get it to compile as it seems to depend on cowsql which isn’t building.

Was that using the ebuild?


please open a new bug at with emerge --info and your build.log file attached. Or post them here - but has a better chance for us Gentoo maintainers to notice it.

I can confirm cowsql and incus builds and works on Gentoo.


Yes, from ebuilds. Incus 0.2-rc1 was masked and I think requires some testing version of it’s dependencies so it’s not a simple emerge to get it loaded. And probably not a problem for the maintainers. I’m sure I just need to figure out the correct packages. Gotta love Gentoo.
Thanks for the info.

So, did get it to build using test packages for the dependencies cowsql and raft, but when running …

$ incus admin init

got …

$ sudo incus admin init

Looks like I’m running into some sort of iptables issue and getting 403’s for trying to get to the Incus documentation. :frowning:

Got that part fixed at least :slight_smile:

The error you’re getting seems to suggest that your kernel doesn’t have the module necessary to attach comments to firewall rules. I believe that is CONFIG_NETFILTER_XT_MATCH_COMMENT

Apparently that’s no longer an option as I look through a 6.1.19 kernel.

root@castiana:~# grep -i comment /boot/config-6.6.1-zabbly+ 

It’s still a thing in 6.6.1

I’m not having much luck with Incus on Gentoo and can’t provide much feed back off of the stale ebuilds so I’ve cloned the source, but have no experience with Go. What does it take to build the tree after cloning?

Basically, make sure you have a recent version of Go installed, make sure you have the various dependencies installed, then run make deps and make to get things built.
