I'm using a fresh installed Ubuntu 18.04 on a PC, which mainly uses a wired network, but a wifi connection is also needed from time to time. For that, I'm using a wifi dongle - which works OK when dual boot as Windows, but when using Ubuntu: it DOES detect networks at home- but does NOT connect any.



TP-Links site refers to driver installation, includig a well detailed instructions doing so link to TP-LINK driver, which fails at very beginning as shown below at ATTCH #1.



Second try: referring to an almost exact problem posted here, but again, fails again at make



Appreciate you kind help

          pylint3 and pip3 broken

          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I have tried sudo apt remove --purge on various packages. I get the same when I reinstall. I have also tried reinstall using aptitude. This does not work. My current workaround is to run pylint3 as root, which works, but is bad practice. pip3 $ pip3 Traceback (most recent call last): File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored __import__(vendored_name, globals(), locals(), level=0) ImportError: No module named 'pip._vendor.pkg_resources' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/bin/pip3", line 9, in <module> from pip import main File "/usr/lib/python3/dist-packages/pip/__init__.py", line 13, in <module> from pip.exceptions import InstallationError, CommandError, PipError File "/usr/lib/python3/dist-packages/pip/exceptions.py", line 6, ...

          How to enroll fingerprints to Ubuntu 17.10 with VFS491

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha).

The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
