After kernel update to my OS this tmux configuration exists in error

[lemiesz]

For the past year or so I have been using this configuration with tmux 2.8. It worked fine, however after a system update to my machine today, it has stooped working.

I get the notification "this configuration required tmux 2.3+".

Anyone know whats up?

Even downgrading to 2.3 seems to give me the same message

Hello @lemiesz 👋

Can you please tell me which operating system you're using and the tmux version?

$ tmux -V

Then

$ cut -c3- ~/.tmux.conf | sh -sx

Im on Amazon Linux 2 which a flavor on top of rhel5/centos

NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2:-:internal"
HOME_URL="https://amazonlinux.com/"
VARIANT="internal"

tmux -V

tmux.orig 2.8

Although I also have a tmux 2.3 version installed that does the same thing.

The second command gives me

+ :
+ set -e
+ unset GREP_OPTIONS
+ export LC_NUMERIC=C
+ LC_NUMERIC=C
+ printf ''
+ sed -E s///
++ uname -s
+ _uname_s=Linux
++ tmux -V
++ tr -cd 0123456789.
++ cut '-d ' -f2
++ awk -F . '{print $1 * 100 + $2}'
+ _tmux_version=2
+ command -v pkill

$ tmux -V
tmux.orig 2.8

So you aliased or symlinked tmux?

In any case, can you please try the gh-457 branch? This should improve version detection and fix the problem you're facing.

Hey @lemiesz 👋

Did you find the time to give the gh-457 branch a try by chance?
