Ubuntu 20.04.2 LTS error with "python-backports.ssl-match-hostname" package

[Virgus]

Hello, I've been struggling for hours to try to overcome this error.

TASK [Ensure dependencies are installed.] ************************************** fatal: [127.0.0.1]: FAILED! => changed=false msg: No package matching 'python-backports.ssl-match-hostname' is available

I've been trying to follow all the suggestions I found on the web but none worked. There doesn't seem to be a "python-backports.ssl-match-hostname" ubuntu package for 20.04 LTS (I'm using an x64 version on an SSD booted RPi4) and I also tried installing the package through python2 and pip2.

pip2 --version gives the following output: "pip 20.3.4 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)"

sudo pip2 install backports.ssl-match-hostname gives: "Successfully installed backports.ssl-match-hostname-3.7.0.1"

So the package seems to be there but when running "ansible-playbook -c local main.yml" it still seems unavailable.

Before giving up I'm wondering if anybody faced and solved the same issue... Thanks, any help would be greatly appreciated. V.

I just found your old issue comment: https://github.com/geerlingguy/drupal-pi/issues/41#issuecomment-510317536 I tried uninstalling python2 and both pip2 and pip3 and re-installed everything but nothing changed :-(

@Virgus - Just to note, I haven't tried this playbook on Ubuntu for Pi before, only Raspberry Pi OS. Some packages might be different between the two.

@geerlingguy many thanks for your prompt reply, I'm aware that it's not a common issue of a common setup. I had to choose Ubuntu Server at the time for my Docker RPi because of the lack of a solid x64 OS.

Despite of the "small issue" here, I'm afraid that it's solution is beyond my current skills. I ended up installing drupal on a Win10 Docker install but it seems so slow compared to Raspberry 4 !

Cheers, V.

@Virgus I had the same problem, in tasks/init.yml - just comment out the line # python-backports.ssl-match-hostname and it seems to work fine

I experience the same problem on my RPI 3 with the newest Raspberry Pi OS installed. Manually installing it via "pip3 install backports.ssl-match-hostname" did not help. What exactly would this be needed for? I guess not having it installed could cause some problems with specific host name configurations... Commenting out the line in tasks/init.yml as suggested by @debeshmandal solved the problem in this installation step, will this how it works out when I continue the installation later / check the installed drupal later.

I do not know if this is related to this issue, but it probably is a misconfiguration of the hostname.

When I navigate to a hostname that I specified in /etc/hosts, the browser shows this:

@TheRealMephisto - Note that's often a problem with Drupal 8/9 in some cases after initial installation. I've found that logging into the Drupal container on the command line and running a drush cr to rebuild caches sometimes fixes that up. No clue why it only happens sometimes.

Hello et-all, Latest version of Buster CLI only and got the same error. Commenting the magic line worked for me..
