I did some more tests and finally found the culprit: it was libice package! Instead upgrading the system at once, I upgraded package after package, one after one, until I find out which one was causing the problem. When I upgraded libice-1.0.9-2 to libice-1.0.10-1 I couldn't start Trinity. Once I downgraded it back to 1.0.9-2 Trinity worked normally again. For now I will keep the old version of libice in my system. On Mon, 22 Jul 2019 at 04:21, David C.
