I am trying to remove some old repositories form SLES 11.3. If I try deleting with YAST it seems to work, but when I use YAST again to configure the repositories the ones I removed are back again. If I use 'zypper rr' to remove them it seems to work because 'zypper lr' does not show them anymore. However if I again use YAST to configure the repositories, the ones I removed are there again and if if run 'zypper lr' they are all back.
