package python3 3.6.5-3ubuntu1 failed to install/upgrade: installed python3 package post-installation script subprocess returned error exit status 4

[Carlos Sotto Maior]

E: py3compile:183: cannot create directory /usr/share/hplip/ui5/__pycache__: FileNotFoundError(2, 'No such file or directory')

The above erro line was the first error in the Synaptic update process.

There are subsequent erros 2 and error 4 messages but I am assuming that they are consequences of this first error.

I have first updated all available SOFTWaRE UPDATES and then started Synaptic >> Mark all updates >> Install.

Thanks for your attention in analysing this message.
