Unable to set timezone in linux

By default, the time is updated when I connect to the internet and the timezone is set to UTC.

I want to change it to “Asia/Kolkata” but I get an invalid timezone error. I do not have the external RTC powered. How can I fix this?

sh-4.4# timedatectl list-timezones | egrep -o "Asia/K.*"
Asia/Kabul
Asia/Kamchatka
Asia/Karachi
Asia/Kathmandu
Asia/Khandyga
Asia/Kolkata
Asia/Krasnoyarsk
Asia/Kuala_Lumpur
Asia/Kuching
Asia/Kuwait

sh-4.4# timedatectl set-timezone "Asia/Kolkata"
Failed to set time zone: Invalid time zone 'Asia/Kolkata'

Hi,

I already tried that but I get the following output:

Collected errors:

        But that file is already provided by package  * tzdata

So I removed tzdata and tried again. Not working.

Hi @jaski.tx,

I got it to work. I had to remove tzdata first because it causes clashes at “Bangkok”. I also had to remove tzdata-asia, since it had been installed incorrectly in the earlier attempts. This was my problem. After ensuring that both had been removed, the rest worked as expected.

Did you also have to uninstall tzdata?

Thanks

Perfect that it is working.

Yes.I removed tzdata too.

Best regards,
Jaski
