Mint 20: Cannot upgrade 5.0 to 5.1

[ysageev]

I know Mint/Ubuntu is not officially supported, but...

I had no trouble installing pihole on Mint 18 and upgrading to 5.0 on Mint 18. Then I upgraded to Mint 20. pihole 5.0 works fine but when I try to upgrade to 5.1 I get the OS_UNSUPPORTED error and setting the environment variable doesn't help. Attached is my debug log (upload/token didn't work).

pihole-debug-log.txt (69.8 KB)

I'm running the OS on a VM in ESXi 6.7

What I have changed since installing Pi-hole:

1. The upgrade to 5.0 overwrote the static IP and port assigned to lighttpd, which I restored by editing lighttpd.conf.

Mint is not an officially supported OS. Since v5.1 this is pointed out to the user more directly.
Try

export PIHOLE_SKIP_OS_CHECK=true pihole -up

I mentioned "setting the environment variable doesn't help". I should have been more explicit. The result of doing so has no effect -- it still tells me that OS not supported.

Someone was successful using

sudo export PIHOLE_SKIP_OS_CHECK=true pihole -up

I cannot update to Pihole 5.1 on OSMC

Hi I am using OSMC 2020.06-1 and I cannot perform the upgrade of Pihole. When I do: pihole -up I get: [✗] Unsupported OS detected Redirecting... This check can be skipped by setting the environment variable PIHOLE_SKIP_OS_CHECK to true e.g: export PIHOLE_SKIP_OS_CHECK=true By setting this variable to true you acknowledge there may be issues with Pi-hole during or after the install If that is the case, you can feel free to ask the community on Discourse with the Community Help catego…

Thank you! It worked!

Note: It's not
sudo export PIHOLE_SKIP_OS_CHECK=true pihole -up

but

sudo PIHOLE_SKIP_OS_CHECK=true pihole -up
