Hi,

I upgraded my server Ubuntu from 14.04 to 16.04. After that when I ran bench update I got the following error:

frappe@physiotouch:~/frappe-bench$ bench update INFO:bench.utils:updating bench Already up-to-date.

I did try to install the recommended packages:
Please install these dependencies using the command:
sudo apt-get install -y libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

I had already those installed. Could this be due to problem with pip? Any ideas how to fix this?
Appreciate any help, thanks.

Please install these dependencies

Hi,

Thanks for the reply.
I did try that and I had everything up-to-date.
Could this be something to do with python2 vs python3?

Hi,

Could any one help me on this issue?

This seems to an be issue relevant to the virtual environment setup, caused by it not finding datetime after the upgrade.
Try running
$ cp /usr/bin/python2.7 $(which python2.7)
to fix it.

More info: Python: no module named datetime? - Ask Ubuntu
python - ImportError: No module named datetime - Stack Overflow

same error here…
tried to fix with

cp /usr/bin/python2.7 $(which python2.7)

got message “are the same file”

Another probable way would be to reinitialise the virtualenv by:
$ cd /home/frappe/frappe-bench/env/ $ virtualenv .

Hi @pratu16x7

I encountered the same errors here but after following the steps outlined above, I’m now getting the error below when trying to run bench update

It says something about “Too many levels of symbolic links”. Any assistance will be much appreciated as the site is currently not accessible

Thanks

Hi @pratu16x7

I solved the issue by doing ‘rm bin/python*’ from the /home/frappe/frappe-bench/env/ folder and then did the ‘virtualenv .’ again and everything worked this time

Cheers!
