Hi. I've upgraded Buinic to Eoan and encountered an error with apt-get. Decided to have a fresh install of Disco from https://dl.armbian.com/orangepizero/ and got exact same error. 

I did nothing with the installation except that I've configured WiFi with ntmui-connect command.

So I guess this is some issue with Ubuntu releases 19.xx

maybe this page could help a little bit?:

No, I tried that - it didn't resolve the issue. I also considered a theory that an upgrade messed python 2.7 and 3.6 - didn't solve my problem as well.

on my OrangePi One creator.py is at

root@opi-one(192.168.6.114):/ # find / -name *creator*
/usr/share/command-not-found/CommandNotFound/db/creator.py

and cnf-update-db is as a symbolic link at the right place 

root@opi-one(192.168.6.114):/usr/lib# ls -l cnf*
lrwxrwxrwx 1 root root 40 Nov 21  2018 cnf-update-db -> ../share/command-not-found/cnf-update-db

so whats the error after

sudo cp -r /usr/share/command-not-found/CommandNotFound /usr/lib/python3/dist-packages/

 

I will check in a moment. Currently trying other distributions. Found out that there is no wireless connectivity on Armbian_19.11.3_Orangepizero_buster_current_5.3.9 (nmtui-connect only displays "Wired connection 1").

your problem is just one thread aways (from the actual one's):

As I said in this other thread :

Quote

In my case, I'm using "old school" /etc/network/interface, running Stretch 5.4.2, and WiFi running properly as soon as I disabled NetworkManager service.

 

Re-installed Disco, wireless connectivity worked, but apt-get update produces error. Checking:

 

root@orangepizero:~# cd /usr/lib
root@orangepizero:/usr/lib# ls -l cnf*
-rwxr-xr-x 1 root root 684 Nov  9  2018 cnf-update-db
root@orangepizero:/usr/lib# find / -name *creator*

root@orangepizero:/usr/lib# cp -r /usr/share/command-not-found/CommandNotFound /usr/lib/python3/dist-packages/
cp: cannot stat '/usr/share/command-not-found/CommandNotFound': No such file or directory

Tried

sudo cp -r  /usr/lib/python3/dist-packages/CommandNotFound /usr/share/command-not-found/

and also 

 

sudo cp -r  /usr/lib/python3/dist-packages/CommandNotFound /var/lib/command-not-found/

Error is caused by /usr/lib/cnf-update-db in the line 165, which reads:

        # read header
        suite=tagf.section["suite"]

and then causes error in line 127, which is

 

    def _fill_commands(self, con):
        for f in self.files:
            with open(f) as fp:
                self._parse_single_commands_file(con, fp)

As far as I can understand, it works with this list of files:

To double-check, wiped the SD card and burned the image again. On fresh system:

The /usr/lib/cnf-update-db throws error "out of the box": I never ran apt-get, I even haven't set up networking - it is "dead on arrival".

it is "dead on arrival".

Non-LTS Ubuntu releases are not supported anyways. The ability to built those through the build system has been added by user contribution. They are to be considered experimental.

Exactly. Anything out from Bionic and Buster is not supported / on your own risk. We have no intention nor resources to fix after buggy Ubuntu development and/or non LTS releases. But if one like to use it, use it ... 

 

Since last major upgrade, DISTRIBUTION status is getting a property and if you are running not one of them, you also get prompted:

Well, my intention was to use Debian Buster, but its wifi connectivity is broken, so I had to start shopping around.

Canonical / Ubuntu / Debian / * are not responsible for low level (hardware) functions, (Armbian) Linux kernel is. We provide different user space versions (Debian X, Ubuntu Y) for application level.purposes and testings. Wifi on this board is low/barely usable quality even when available.

This error rears its ugly head again in Focal 20.04LTS with the OPi0.

 

Googling for results for this error (it's exactly the same) gives exactly one google result - this thread.

 

So, for anyone else stumbling over this, here the solution:

 

sudo apt purge command-not-found
sudo apt --purge autoremove
sudo bash -c 'apt update && apt full-upgrade && apt autoremove && apt clean'

Unfortunately, a reinstall of the pkg 'command-not-found' brings back the same error.

 

This package is just for comfort. If you need suggestions for installing packages after entering nonexisting commands, just use another computer for reference. I advise to just leave it uninstalled for now.

 

Seems there are some hits:

https://bugs.launchpad.net/ubuntu/+source/command-not-found/+bug/1876034

 

That one includes a patch that could be applied.
