This question already has an answer here:

Ubuntu 18.04 Thunderbird updated automatically to 60.2.1 two days ago. With two problems for me:

  • UI language changed from en-US to Dutch, so all short cuts I use are different..
  • calendar was not present any more.

I added the en-US version of Thunderbird. As explained here, I simply extracted a tar: https://support.mozilla.org/en-US/kb/installing-thunderbird-linux Now the short cuts I know work again and the calendar is back. Fine.

I think I can manage to add the en-US version to the launcher (or live without). Less ideal is that it will not automatically update. But I do want it to do automatically updates. So I guess that I'd rather replace the installed version (I think in /usr/lib/) with the en-US that I just unpacked. How can I do that?

Some info:

  • It might well be that there is no default installed Thunderbird and that I did it myself.. years ago, sorry that I do not remember that. – cor4office Oct 17 '18 at 20:18

My question above was way too verbose. I wrote a short and clear version. That has been answered. See replace default Dutch Thunderbird by en-US version Please close this question as duplicate - someone with proper rights.

  • Not only way too verbose, but also bit of an XY problem imo. – pomsky Oct 20 '18 at 13:37
