NCP unable to upgrade from 1.8.0 to 1.9.1 (letsencrypt)

NextCloudPi version v1.8.0
NextCloudPi image NextCloudPi_06-27-18
distribution Raspbian GNU/Linux 9
Nextcloud version

When running ncp-update it fails with:

Downloading updates
Performing updates
Running letsencrypt
empty domain

I have not configured letsencrypt locally and have not, intentionally, enabled it.

I do use letsencrypt certificates, I generate these via dns-01 elsewhere, so there are /etc/letsencrypt/live and archive dirs with the certificates in.

I can’t see how to disable any local letsencrypt processes or get this upgrade installed.

Any help appreciated.

I can also not upgrade from 1.8.0 to 1.9.1. Running

sudo ncp-update

gives the following output

Downloading updates

Maintenance mode enabled

Running letsencrypt
/usr/local/bin/ncp/NETWORKING/ line 62: /etc/letsencrypt/letsencrypt-auto: No such file or directory
pi@nextcloudpi:~ $ sh: 0: getcwd() failed: No such file or directory

Any possible solutions?

From other threads check in /etc/ and see if you have other letsencrypt directories.

I suspect you may find /etc/letsencrypt or /etc/letsencrypt-old

In which case copy/renaming/linking whichever has the newer certificates to /etc/letsencrypt/letsencrypt-auto may resolve your issue.

Mostly the same with my ncpi, except I do NOT use letsencrypt (so far). It seems as if it doesn’t check for that case and thereby “demands” using let’s encrypt.

I noticed that within ncp-config there is a * at the menu item letsencrypt suggesting it is activated, though, as I mentioned, I haven’t activated it at any time.

Is there something I can do to successfully update anyway?

From the downloaded it looks like

fix LE cron

is_active_app letsencrypt && run_app letsencrypt

is always being run.

Good point, and it appears that this line was introduced in 1.9.1, so maybe me, having that issue despite

is_active_app letsencrypt

may correlate with letsencrypt being falsely displayed as active in my ncp-config menu.
Is there a way to correct the status of the app letsencrypt?

My certificates are placed in /etc/letsencrypt/live/

I created a link from my certificates accordingly

sudo ln -s /etc/letsencrypt/live/ /etc/letsencrypt/letsencrypt-auto

and then again when I try to ncp-update I get

Downloading updates
Performing updates
Running letsencrypt
/usr/local/bin/ncp/NETWORKING/ line 62: /etc/letsencrypt/letsencrypt-auto: Is a directory

That looks like a bug (and you can remove the link you created).

/etc/letsencrypt/letsencrypt-auto looks to be where the letsencrypt/certbot executable files should now to be located .

However from /usr/local/bin/ncp/NETWORKING/ letsencrypt (as a parameter) is set to point to this directory:


And in line 62 is used:

$letsencrypt certonly -n --no-self-upgrade --webroot -w $ncdir --hsts --agree-tos -m $EMAIL -d $DOMAIN && {

Which should be $letsencrypt/[COMMAND] -params … etc.

Which is why you are getting your error.

what is the output of find /etc/letsencrypt/live/ for you?

The error output, while ncp-update, is

find: ‘/etc/letsencrypt/live/’: No such file or directory

GCsFfoz5 so is there something I could do to workaround this bug? Or do u believe I should just wait for the next update?

I would expect line 62 to read something like

$letsencrypt/certbot certonly -n --no-self-upgrade --webroot -w $ncdir --hsts --agree-tos -m $EMAIL -d $DOMAIN

I see, easy fix. Please try again

If you don’t have this file /etc/letsencrypt/letsencrypt-auto, then you have taken too long to update, so now you are stuck with the old letsencrypt

Try this snippet to install the latest version

  source /usr/local/etc/                                                                                                                                                                                                                                                                                               

  [[ -f /etc/letsencrypt/certbot-auto ]] || {

    [[ -f /.docker-image ]] && mv "$(readlink /etc/letsencrypt)" /etc/letsencrypt-old
    [[ -f /.docker-image ]] || mv /etc/letsencrypt /etc/letsencrypt-old
    rm -f /etc/letsencrypt
    apt-get remove -y letsencrypt
    apt-get autoremove -y
    install_app letsencrypt
    [[ -f /etc/letsencrypt-old/live ]] && cp -raT /etc/letsencrypt-old/live /etc/letsencrypt/live
    [[ -d /etc/letsencrypt/archive ]] || \
   cp -ravT /etc/letsencrypt-old/archive /etc/letsencrypt/archive &>/dev/null
    [[ -f /.docker-image ]] && persistent_cfg /etc/letsencrypt
    [[ -f /etc/cron.weekly/letsencrypt-ncp ]] && run_app letsencrypt

re-installing letsencrypt makes no difference to the 1.9.1 update.

It still runs letsencrypt and fails reporting empty domain.

As /etc/cron.weekly/letsencrypt-ncp does not exist on my system is there anything else that can be done to completely disable letsencrypt?

Fixed my issue, works like a charm. Thank you very much.

@GCsFfoz5 No luck with changing line 62. Actually I sudo nano and change the line as you advice but when I go into the file again the change is not saved. of course running again ncp-update gives the same result.

@nachoparker I also did not have the file etc/letsencrypt/letsencrypt-auto . Was there a version between 1.8.0 and 1.9.1? I created a script with the code snippet for reinstalling letsencrypt but what I get is

guys sorry but my knowledge of linux is limited so some things I say or do may not make sense

With what @nachoparker posted above the original script is correct.

If you run the snippet above it will install the new letsencrypt binaries

After that you can re-run the original script.

SOLUTION (for me)

  1. To de-activate letsencrypt from NextCloudPi Panel

If letsencrypt is showing as active in NextCloudPi Panel. I.e. has a tick by it, you can de-activate it by
moving, renaming or deleting the config file /usr/local/etc/ncp-config.d/letsencrypt.cfg

  1. To get NextCloudPi to upgrade from 1.9.1 (after a failed upgrade)

backup anything you need in /etc/letsencrypt

remove all contents of /etc/letsencrypt

run ncp-config (fails)

remove all contents of /etc/letsencrypt

run the snippet above from @nachoparker

run ncp-config (succeeds)


T h a n k You! I really appreciate you taking the time to write a step by step solution! It worked!
