Comment 2 Katerina Koukiou 2021-01-21 16:17:43 UTC
Yunming I am not sure what you mean by jam. The design of the VMs page has drastically changed since 197,specically in Cockpit 231 with https://github.com/cockpit-project/cockpit/pull/14346.
I am suspecting that in the new design the issue you describe does not exist.

Comment 3 YunmingYang 2021-01-21 17:20:00 UTC
The issue means that the progress bar in the installation dialog get stuck. And in the past version, it will be recovered if we switched to another tab and switched back. For now, I try several times in cockpit-machines-235, the issue seems to disappear.

Comment 4 Martin Pitt 2021-01-22 07:06:40 UTC
