"breakfast kltekor" fails.

[spamrefuse]

Hello,

I tried to compile LOS21 UL myself, following the standard AOSP / Lineage procedure.

When I do the "breakfast kltekor" command, this fails as follows:

=====================

** Don't have a product spec for: 'lineage_kltekor'
** Do you have the right repo manifest?

There is no lineage-21 branch for kltekor. However, on the xda developer forum, this LOS-UL reporsitory is given for the LOS21 kltekor ROMs.

Am I doing something wrong?
