Downgrade multiple timezones to warning instead of error?

[hmaarrfk]

I'm not sure if this is an ubuntu 24.04 bug or a tzlocal bug, but here are the steps to recreate

$ echo "/etc/timezone $(cat /etc/timezone)" && ls -lah /etc/localtime
/etc/timezone America/New_York
lrwxrwxrwx 1 root root 36 Sep 20 11:11 /etc/localtime -> /usr/share/zoneinfo/America/New_York

Then go to the Ubuntu date and time settings and uncheck automatic timezone and change the timezone to be something else

$ echo "/etc/timezone $(cat /etc/timezone)" && ls -lah /etc/localtime
/etc/timezone America/New_York
lrwxrwxrwx 1 root root 39 Sep 20 08:12 /etc/localtime -> /usr/share/zoneinfo/America/Los_Angeles

Then you can't import your code anymore because the /etc/localtime and /etc/timezone conflict.

Would it be OK to let /etc/localtime take precedence and make the error below a warning instead of an error? Setting environment variables is somewhat annoying.

Thank you for the consideration

I can confirm that if you run:

sudo dpkg-reconfigure tzdata

and press enter twice, it will fix things..... somewhat annoying....

mark@carbon $ sudo dpkg-reconfigure tzdata
