I'm having errors upgrading to Pop_OS 20.04 from 19.10.

Here's what I see when I sudo apt update:

[...] Err:19 http://us.archive.ubuntu.com/ubuntu eoan/main amd64 c-n-f Metadata lzma_read: Read error (7) [...] Fetched 255 kB in 1s (190 kB/s) Reading package lists... Done E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/eoan/main/cnf/Commands-amd64 lzma_read: Read error (7) E: Some index files failed to download. They have been ignored, or old ones used instead.

and when I sudo pop-upgrade release upgrade systemd:

```

sudo pop-upgrade release upgrade systemd

Event: removing deprecated and/or conflicting packages Event: updating package lists for the current release Release upgrade status: release upgrade aborted: failed to update package lists for the current release: command failed with exit status: exit code: 100 pop-upgrade: dbus client error: calling ReleaseUpgradeFinalize method failed ```

I have no external PPAs configured in /etc/apt/sources.list.d.

It looks like apt is having trouble reading from one of the repositories for some reason (lzma_read: Read error), but when I visit that actual URL there doesn't seem to be an issue getting anything or unzipping anything.

I'm unclear if this is what's stopping pop-upgrade from working since I can't find any way to enable more verbose logging. Any hints about how I can get the upgrade working?
