Comment 2 for bug 1880261

Relevant error message (from DpkgTerminalLog.txt):

error: cannot perform the following tasks:
- Download snap "chromium" (1165) from channel "stable" (read tcp 192.168.1.28:52856->91.189.88.178:443: read: no route to host)

This looks like a transient network failure. Can you please try reinstalling the package?

    sudo apt reinstall chromium-browser
