Hello 🙂
When trying to install an app, install fails because of an issue with doveadm. Trying the command alone raise the same result:
> doveadm -f flow quota get -u MyUser
> doveadm(root): Fatal: Unknown command ‘quota’, but plugin quota exists. Try to set mail\_plugins=quota
I tried to remove and re-install dovecot, no change.
Do you know how I can fix this issue ? Thanks 🙂

Which YunoHost version is used ?
For the moment I think you can work around by stopping dovecot

Note: if dovecot is stopped, you won’t be able to download your email.

I used 2.4, now updated to 2.5, no change.
Ok, I’ll test that 🙂

What is the result of this command
```
sudo doveadm -f flow quota get -u USER
```
Replace USER by a yunohost user of your server

I think your quota plugin is not setup due to an arm specificity (may be because recommends package are not set up)
Try to run `grep mail_plugins /etc/dovecot/dovecot.conf`. You should get this:
```
root@yunohost:/home/vagrant# grep mail_plugins /etc/dovecot/dovecot.conf
mail_plugins = $mail_plugins quota
mail_plugins = $mail_plugins imap_quota antispam
mail_plugins = quota sieve
```

The result is empty 😕

can you install “dovecot-sieve” ?
[sudo apt install dovecot-sieve]
Then, give the result of "grep mail\_plugins /etc/dovecot/dovecot.conf ".

strange !
May be you or an app change the dovecot conf ?
If you want watch differences:
yunohost service regen-conf --with-diff dovecot
If you want restore the dovecot conf:
yunohost service regen-conf --force dovecot
