Comment 8 for bug 1951705

Hi everyone,
i followed your thread and
i've the same error as reported above on my Raspberry Pi 4 with ubuntu server 20.04.
Now I can confirm that the above pull request solved the (and my) problem!
I changed the package on my system, applied the patch/fix manual with the GitHub PullRequest fix and my install worked!!!.
So please merge the GH PR and everything will be fine.

Here's my steps and output:
