Re: How to update to the latest Tailscale version?

I am on latest released Netgate 6100 pfSense PLUS v24 ( pfSense_plus-v24_11_amd64-pfSense_plus_v24_11 )

pkg config abi
FreeBSD:15:amd64

pkg -vv | grep -A 3 "pfSense:"
  pfSense: {
    url             : "pkg+https://pfsense-plus-pkg.netgate.com/pfSense_plus-v24_11_amd64-pfSense_plus_v24_11",
    enabled         : yes,
    priority        : 0,

cat /usr/local/etc/pkg.conf
ABI=FreeBSD:15:amd64
ALTABI=freebsd:15:x86:64
PKG_ENV {
	SSL_CA_CERT_FILE=/etc/ssl/netgate-ca.pem
	SSL_CLIENT_CERT_FILE=/usr/local/etc/pfSense/pkg/repos/pfSense-repo-0001-cert.pem
	SSL_CLIENT_KEY_FILE=/usr/local/etc/pfSense/pkg/repos/pfSense-repo-0001-key.pem
}

This firewall is obviously running on FreeBSD 15 no longer on 14.

But can I use the freshports link for FreeBSD 14 amd64 quarterly which is at tailscale 1.86.2 or can I only go up to version tailscale 1.84.2_1, and need to wait until they have a version of tailscale 1.86.2 or higher for the FreeBSD 15?

Would it be good enough to tell it to ignore the OSVERSION?

export IGNORE_OSVERSION=yes

Note: use of 14 and not 15 ?

pkg add https://pkg.freebsd.org/FreeBSD:14:amd64/quarterly/All/tailscale-1.86.2.pkg

service tailscaled restart

tailscale up

If the package is a simple bash script, or something light like that, maybe.
The pkg too will complain for sure, probably a lot. Still be ready to lose your system.

If the package contains binaries : forget it. The ABI is different. Package dependency night mare get introduced, consider your system as "alien ware" (not the brand) from now on, even it somehow seems to work.

@Gertjan Thanks. This is a compiled binary the tailscale vpn network mesh using wireguard. So this is s definite no then.

@Gertjan said in can I install a FreeBSD 14 pkg on a FreeBSD 15 pfSense?:

It's not a hard and fast rule like that. It depends upon what the binary is, what dependencies it has, and how everything was compiled.

I am currently running a binary package, which was built on FreeBSD 14.2-RELEASE, on pfSense 25.07 (FreeBSD 15.0-CURRENT) without issue.
