@viktor Same thing happening for me with pkgupdate failing. It seems to happen because it thinks I have no additional package lists enabled.
EDIT:
Done some more research, and it seems like the pkglists formatting has changed slightly. @Pepe I’m assuming this is what the fix-pkglists-options package was supposed to fix? But it looks like what it’s done is break the config file. For reference, this is what my /etc/config/pkglists looks like:
config pkglists 'pkglists'
config pkglist 'nas'
option samba '1'
option dlna '1'
option transmission '1'
option raid '1'
option encrypt '1'
If I change it to:
config pkglists 'pkglists'
list pkglist 'nas'
config 'nas'
option samba '1'
option dlna '1'
option transmission '1'
option raid '1'
option encrypt '1'
It works again.
