Pakfire reports errors during 'tmux 3.3' upgrade - but why?

Hi,

Pakfire likes to have a problem. ;-)

...not worried - just being curious...:

Today I stumbled upon a 'tmux' update. Pakfire reported that 'tmux-3.3-10.ipfire' was available.

CGI looked normal, installation went through.

But Pakfire didn't close, reporting: 'Pakfire has finished! Errors occurred, please check the log output before proceeding.'

I looked through the log, but can't find anything critical (screen log is attached).

What triggered this message!? 'tmux 3.3' was installed, everything seems fine, but Pakfire complains.

Any hints are welcome.

Best,

Matthias
