found 1128320 5.20.5+dfsg-1 thanks Hello Andreas. As I see you have fixed this in salsa:
Currently tracker says this: help 5.20.5+dfsg-2 (9 days old) ∙ Updating libsbml would introduce bugs in testing: #1128320 but that's not really true because testing is also affected. The above command might help version -2 to propagate to testing in case your plan is to upload -3 after such propagation happens. Thanks.
