unrecognized arguments: --preferred-chain

Asked by Omacka S

I would need to use certbot --preferred-chain "DST Root CA X3" argument, but i'm getting error: unrecognized arguments
versions are: ubuntu 20.04, certbot 0.40.0 (0.40.0-1ubuntu0.1)

if i install certbot via snap i get certbot 1.10.1 and there is no problem whith that argument...

I don't understand why ubuntu and "genuine" certbot are not the same... it seems they are two different tools...?
Please do we know when the ubuntu packages will support "--preferred-chain" argument?

thank you

The option "--preferred-chain" is supported by certbot version 1.7 (in Ubuntu 20.10 groovy) but not in certbot 0.40 (in Ubuntu 20.04 focal).

Can you help with this problem?
