Did a fresh install today.

When it came to installing byobu, I installed all python3 related packages pulled in by byobu first, then I installed byobu and had no issues.

Note, this is for the arm64 Beowulf Raspberry Pi version.

My i386 Beowulf version had no issues installing byobu and pulling depends.

Could be user error, or some bug in how the packages are pulled in and configured... but it works now.

Not sure, it's not on right now. I'll do a fresh base install tomorrow and get back to you.

Works for me:

Are your python versions linked correctly?

Here are mine for reference:

empty@thanatos:~ $ ls -l /usr/bin/python{,2,3}
lrwxrwxrwx 1 root root 7 Jan 18 10:56 /usr/bin/python -> python2
lrwxrwxrwx 1 root root 9 Jan 18 10:56 /usr/bin/python2 -> python2.7
lrwxrwxrwx 1 root root 9 Jan 18 07:54 /usr/bin/python3 -> python3.7
empty@thanatos:~ $

Otherwise perhaps try re-installing the python packages:

# apt reinstall $(dpkg -l|awk '/^i/&&/python/{print $2}')

Raspberry Pi 3 install successful and fine.
Upgrade to Beowulf had no issues.

I go to install byobu and run into this issue.
