Dear DRC, here are the exact steps. In September I’ve upgraded from 20 to 22. I had TurboVNC 2.x and after the upgrade I’ve also update to the last version that was 3.03. No problem and all started to work smoothly.
On Friday I had to further upgrade because I’ve received a vulnerability report from my ICT admin because of the OpenSSH version 8.9. So I had to update to 9.3 that is supported by UBUNTU 24. After the upgrade I had the TurboVNC version 3.03 already installed and I’ve received the same error, this is because I update to 3.1. So, at my knowledge, at least TurboVNC 3.03 has the issue. Actually, I cannot try the older versions because the machine is shared. What I guess is that it might be a problem due to the fact that I don’t have a fresh installation but a 2 times updated version of Ubuntu… Thanks a lot Andrea Farina > Il giorno 22 dic 2024, alle ore 17:35, 'DRC' via TurboVNC User > Discussion/Support <turbovnc-users@googlegroups.com> ha scritto: > > > I mentioned TVNC_USERDBUS in case you were using GNOME Classic, but that > environment variable should not be necessary with plain (non-classic) GNOME. > I will try to reproduce the issue, but I may not be able to.
