Control: tags 1072107 + patch Control: tags 1072107 + pending Hi Peter,
I've prepared an NMU for libarchive (versioned as 3.7.2-2.1) and uploaded it to DELAYED/2. Please feel free to tell me if I should delay it longer. Made as well a MR in https://salsa.debian.org/debian/libarchive/-/merge_requests/6 . libarchive requires a DSA, but see the mail from Moritz some days ago. This MR aims to get the ball rolling from top-down first unstable, to bookworm later/same time. Regards, Salvatore
