Upgrade to Xia: throwing prompt to switch to a local mirror; 'requirements is not responding'

Describe the bug
I initiated this upgrade: to Mint 22.1; from Mint 21.0 (Cinnamon). The result seemed to be a bug, or two.

Screenshots

To Reproduce

• Use the Update Manager to initiate the upgrade.
• See what I saw - perhaps; I do not know exactly what is involved in reproducing the bug. The computer at issue is capable and was not under heavy load.

Expected behavior
I expect no message about a mirror and no confusing message about 'Requirements' not responding.

Distribution:

• [X ] Linux Mint

Software version:
6.1.5

Additional information

I clicked 'Wait' and was told that the upgrade had succeeded.

Start with the Update Manager upgrade flow and the supplied refresh log; attempt the reported Linux Mint 21.0-to-22.1 Cinnamon upgrade using software version 6.1.5. Compare the mirror prompt and “Requirements” not responding message with the expected upgrade outcome. Done means the upgrade completes without those confusing messages.
