Hi,

I've have the same problem. I want to delete all the 32 bits channels:

But in the web interface this option is disabled ( section Admin -> Setup Wizard -> SUSE Products ) and the "mgr-sync" doesn't work neither:

# mgr-sync delete "sles11-sp3-pool-i586"
usage: mgr-sync delete [-h] {credentials} [target [target ...]]
mgr-sync delete: error: argument delete_target: invalid choice: 'sles11-sp3-pool-i586' (choose from 'credentials')

# mgr-sync delete "SLES11-SP3-Pool for i586 SUSE Linux Enterprise Server 11 SP3 i686"
usage: mgr-sync delete [-h] {credentials} [target [target ...]]
mgr-sync delete: error: argument delete_target: invalid choice: 'SLES11-SP3-Pool for i586 SUSE Linux Enterprise Server 11 SP3 i686' (choose from 'credentials')

# mgr-sync delete "sle11-sdk-sp3-updates-i586"
usage: mgr-sync delete [-h] {credentials} [target [target ...]]
mgr-sync delete: error: argument delete_target: invalid choice: 'sle11-sdk-sp3-updates-i586' (choose from 'credentials')

It seems that delete option only works for delete SCC credentials:

# mgr-sync delete
usage: mgr-sync delete [-h] {credentials} [target [target ...]]
mgr-sync delete: error: too few arguments


Any idea??

Thanks in advance.
