Thanks for the info, but where do you enter the password when using this method?

As long as your home directory is mounted automatically via /etc/fstab, you should be prompted for the password at boot time.

That's not a bad solution, but it might be simpler to use a client which handles a DNS-challenge.

With DNS-challenges you don't have to worry about webservers, or internal/external firewalling.

Hi. Two things you might want to check, if you haven't already.

See if the "UDMA_CRC_Error_Count" or "CRC_Error_Count" attribute (199) reported by your smartctl is >0 and slowly increasing over time. It's not marked as an error by smartctl and it's easy to miss. It's an indication of a flaky SATA bus connection and I've seen this cause filesystem corruption (I'm guessing because every once in a while CRC will randomly end up OK for a corrupted command).

The other thing is to check if you're running "fstrim". Some SSDs are known to have bugs with that and you might be running a kernel that doesn't yet have a workaround or blacklist for your particular model or SSD firmware version. See https://github.com/torvalds/linux/blob/master/drivers/ata/libata-core.c#L3774.

This helped a lot. Thanks! For a younger Ubuntu (20.04), I also had to mount /sys:

mount --rbind /sys /mnt/sys/

I didn't try the mount -o bind method with sys.

If I understand you correctly, Wine does not let CPS read or write to the Anytone 878.

I have not tried Wine so I can't comment on this.

Does that mean we need to purchase a Windows 10 license and run it from VirtualBox?

You could probably use one of the Windows 10 IE / Legacy Edge testing VMs that Microsoft offers for free for 90 days.
