Hi, I’m deeply impressed from this fine tool.

I did this ask @discord, without an reply, Anyway, posting with code tags is more clear. 🙂

## Environment

Debian Buster native installation. installed netdata with **bash \<(curl -Ss [https://my-netdata.io/kickstart-static64.sh](https://my-netdata.io/kickstart-static64.sh))**

It works so far, but Updates are failing.

## Problem/Question

Updates fails with an Error “Permission denied” every time

```auto
# bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)

```

## What I expected to happen

Can anyone lead me to the solution? What can I do?  
Regards

Hi, @Bernd.

Was it once? This looks similar to [Installation fails with "Tarball checksum validation failed" due to geoblock · Issue #11939 · netdata/netdata · GitHub](https://github.com/netdata/netdata/issues/11939) (a temporary issue we couldn’t debug so far).

I’d suggest re-running the updater manually (or waiting until the next cron run) and checking if the issue is gone or not.

No, the issue persists since some days. I did test it round about 10 times

Have you tried to run the updater script manually?

I think I’ve found the problem - fixed in [fix(updater): checksum validation for static build by ilyam8 · Pull Request #11986 · netdata/netdata · GitHub](https://github.com/netdata/netdata/pull/11986).

Updating should start working fine after the fix is merged.

Now I get this it is getting better

```

Ok, My problem is, I do have the mount option noexec for /tmp  
Must be omitted,  
I did mount /tmp/ -o remount  
then a second try was successul

As a newbie to netdata, I would say build the updater to be called using sh, then there is no harm if someone has mounted their /tmp with noxec, or use a different path…

But otherwise great feature, I’m thrilled.  
Thanks for your time and thanks for netdata.

The updater itself should work fine if invoked with a plain, POSIX-compliant shell, and it should be handling temporary directories correctly (it should try `$TMPDIR`, `/tmp`, and then the current working directory, in that order, searching for the first that is both writable and allows execution). It looks like you may have stumbled across a bug in the updater itself here, independent of the checksum validation issue for static builds.

Hi,  
the Checksum error is here, again

Hm, could be your “netdata-updater.sh” doesn’t contain the fix and the script self auto-update doesn’t work for some reason.

> Mi 19. Jan 09:36:51 CET 2022 : INFO: Checking if a newer version of the updater script is available.  
> Mi 19. Jan 09:36:51 CET 2022 : INFO: Entering /tmp/netdata-updater-XB48GRLcP1

I see no [“Downloading newest version of updater script”](https://github.com/netdata/netdata/blob/28ce8f4445394714077150ea1abc3de2a8a42c27/packaging/installer/netdata-updater.sh#L225) log line.

> Mi 19. Jan 09:36:51 CET 2022 : INFO: Current Version: 00103200100078

The fix is 82nd (since the latest tag) commit:

```cmd
[ilyam@pc netdata]$ git log --pretty="%s (%an)" $(git describe --tags --abbrev=0)..HEAD --reverse | awk '{print "["NR"]\t" $s}' | grep "checksum va"
[82]	fix(updater): checksum validation for static build (#11986) (Ilya Mashchenko)

```

Try

> touch -t 1970-01-01T00:00:00 /opt/netdata/usr/libexec/netdata/netdata-updater.sh

And then re-run the updater script.

I can confirm the autoupdate worked fine last night.
