Updated a snapshot using Attended Sysupgrade and it seem that opkg is missing from the build. (tried via luci and terminal)
root@R7800:~# opkg update
-ash: opkg: not found
Just want to know what my best options are here, do I wait for a new snapshot or try to roll back? Everything else in the build seems to be working so far.
I haven't tested myself, but most likely Attended Sysupgrade (I guess you used the LuCI app?) didn't understand that the opkg package should be replaced by apk, resulting in an image which has neither apk or opkg.
If you don't have apk installed, I guess the simplest way would be to install the sysupgrade again, either SNAPSHOT (then you get apk) or a 24.10 release candidate (then you get opkg). I've been running 24.10.0-rc2 for a few weeks on my own R7800 without any issues.
You could also try to use the LuCI app and manually change the package list in the UI to include apk, that should solve not having a package manager as well.
