Subject: bug#68411: Timezone not detected from /etc/localtime
Date: Fri, 12 Jan 2024 17:41:58 -0500 [thread overview]
Message-ID: <874jfiku6y.fsf@riseup.net> (raw)
Apps such as Icecat or ungoogled-chromium are not able to get the
correct timezone from /etc/localtime when `/etc/localtime` is a realpath
maybe because it expect /etc/share/zoneinfo, with readlink partially
works fine some apps, maybe related with an icu bug.[1]
I just removed manually `/etc/localtime` and crate an symlink `sudo ln
-s $TZDIR/$(cat /etc/timezone) /etc/localtime` and ungoogled-chromium
works fine.
Icecat in other hand has an additional bug related with icu[2][3]
and folder policy where `/gnu` is not allowed so in order to make it
work is necessary disable sandbox `MOZ_DISABLE_CONTENT_SANDBOX=1 icecat`
or set manually TZ env `TZ=$(cat /etc/timezone) icecat`, btw I have
`privacy.resistFingerprinting` false.
The weird thing is that in almost all of those reported the error is
the opposite where having a realpath solves it but in guix it is the
problem, perhaps it could be because these apps have updated their code
to make it work with `icu` v72 and guix has v71.
Steps to reproduce it:
- guix pull && guix package -u
- Install last icecat or ungoogled-chromium version
- Verify that you don't have $TZ set, unset it.
- If it's Icecat open `about:config` and set `privacy.resistFingerprinting` to false
- Open https://webbrowsertools.com/timezone/ in the browser
- Check the timezone
- sudo rm -r /etc/localtime && sudo ln -s $TZDIR/$(cat /etc/timezone) /etc/localtime
- Open chromium or `MOZ_DISABLE_CONTENT_SANDBOX=1 icecat`
- Visit https://webbrowsertools.com/timezone/ again, check the timezone.
