Thanks for your reply. I have the cssu-thumb repo and the cssu-testing repos enabled and I do see an update available, but I get numerous missing package errors when trying to update it. I have attached screenshots of the errors. Apologies for (a) potentially posting in the wrong thread - not sure if this is a cssu-thumb issue, a cssu issue or just a general package management issue, and (b) attaching as screenshots - I couldn't find out how to copy the text from the dialogs. Thank you for any assistance.
