`-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)` on fresh Raspbian on Raspberry

Posted by jpluimers on 2017/03/24

Every time I logged onto a freshly installed Rasbian system (Debian Jessie), I had this message:

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.

-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Asking for the locale settings would give this:

jeroenp@raspberrypi:~ $ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_GB.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

Searching for raspbian jessie “-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)” I found fix locale issue #15 · scaleway/image-debian@543e9b4 [WayBack] that fixes Locale issue on Debian Jessie · Issue #15 · scaleway/image-debian · GitHub [WayBack]:

When logging into to a freshly booted debian jessie image:

-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Source: Locale issue on Debian Jessie · Issue #15 · scaleway/image-debian

I changed the crux of that solution to this one:

echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen && locale-gen

When running, it showed this:

# echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen && locale-gen
Generating locales (this might take a while)...
  en_GB.UTF-8... done
  en_US.UTF-8... done
Generation complete.

And logging this:

Poor man’s MMX: Delphi Live Templates for creating a property with a type which will auto- create the getter/setter

For when you think you can beat Model Maker Code Explorer.

Kylix: The Real Lowdown – I wrote this in 2000 too

Posted by jpluimers on 2017/03/23

A while ago – while researching yesterdays post – I came across the below article that I wrote back in august 2000 for The Delphi (by Pinnacle Publishing – long gone by now) and on-line at http://www.delphidevelopernewsletter.com/dd/DDMag.nsf/WebIndexByIssue/B8FC16D8103A3760852568F600559A83

I found a cached copy first at http://www.txsz.net/xs/delphi/2/%E6%8A%80%E5%B7%A7%E5%8F%8A%E7%BB%8F%E9%AA%8C/KYLIX%EF%BC%9A%20%E7%9C%9F%E7%9B%B8.HTM and back-tracked from there.

Since the wayback machine isn’t indexed, I salvaged the copy below.

On the Delphi Tokyo release yesterday [WayBackTokyo is available today! – Martin Sedgewick – Google+: I will only try that after Update 1 is released, but based on the [WayBackWhat’s New – RAD Studio:

Like

  • Reintroduction of Linux support. Finally.
  • 64-bit as target: server side, the 32-bit days have been over for a long time
  • one-based strings (boy, I’m glad they didn’t continue on the zero-based strings they did on mobile)

Dislike

  • No openSUSE support where SuSE was the primary partner during Kylix development and launch, just search SuSE kylix; heck the registration guide is still up at [WayBackSDB:Kylix – openSUSE
  • LLVM compiler as it is way too slow for my development cycles
  • ARC based

Time will tell if it works better for me than the .NET Core for Linux I’ve been using until now.

Some links on getting a local CollabNet SVN repository to git

Posted by jpluimers on 2017/03/22

A while ago, I had to rescue a project of a developer that had hosted their SVN repository on a locally running CollabNet installation in a VM that wasn’t properly backed up. So besides pollution of a development system, it had to be resurrected after the host crashed. Apparently

Here are some links without full steps that I used to find my way around, find the SVN repository locations and credentials, then convert it to git (that’s now remotely hosted in multiple places both internally and externally).

No steps as hopefully I will never need to take this route again:
