WARN: Duplicate profile ‘Dovecot IMAP’, using last found

Posted on by

So when running ‘ufw’ I was getting this error: WARN: Duplicate profile ‘Dovecot IMAP’, using last found

The issue was duplicate rules were specified in:

/etc/ufw/applications.d/dovecot-core

And:

/etc/ufw/applications.d/dovecot-imapd

The solution for me was to delete the second file (imapd) as it was covered by the previous file (core).

A folder named ~/.cache/kioexec/krun/13821_0/ already exists

On Debian GNU/Linux 9.1 (stretch) when I try to open an *.desktop (application/x-desktop) link in a browser I get:

A folder named ~/.cache/kioexec/krun/13821_0/ already exists.

Searching for:

A folder named kioexec krun already exists

turned up diddly squat.

I solved the issue (for me) by changing:

System Settings -> Personalization -> Applications -> Default Application s-> Web Browser

from:

Open http and https URLs in an application based on the contents of the URL

to:

Open http and https URLs in the following browser: firefox

Salt file.recurse source file not found (file encoding issue)

So I was running this:

/var/www/jj-web-1-www.jj5.net-sixsigma:
  file.recurse:
    - clean: True
    - user: root
    - group: root
    - dir_mode: 755
    - file_mode: 644
    - source: salt://inst/mediawiki-1.29
    - require:
      - pkg: apache2

And getting an error like this:

The issue was that the source files mentioned weren’t in UTF-8 format. To convert the files I ran, e.g.:

$ iconv -f WINDOWS-1252 -t UTF-8//TRANSLIT < module.audio-video.mpeg.php.bak > module.audio-video.mpeg.php

(Actually I couldn’t get the ‘iconv’ command to work so I edited manually in Vim)

Installing .NET on Debian 9

Posted on by

After installing Visual Studio Code I followed the instructions from .NET Tutorial – Hello World in 10 minutes, basically:

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/debian/9/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

Then:

sudo apt-get update
sudo apt-get install dotnet-sdk-2.1

Then for example to create a new console project:

dotnet new console -o myApp
cd myApp

I ended up reading MICROSOFT SOFTWARE LICENSE TERMS for the MICROSOFT .NET LIBRARY which included this doozy:

The software may collect information about you and your use of the software, and send that to Microsoft.

Ah, Microsoft. You haven’t changed.

I found some notes about how to disable telemetry:

Telemetry
———
The .NET Core tools collect usage data in order to help us improve your experience. The data is anonymous and doesn’t include command-line arguments. The data is collected by Microsoft and shared with the community. You can opt-out of telemetry by setting the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to ‘1’ or ‘true’ using your favorite shell.

Read more about .NET Core CLI Tools telemetry: https://aka.ms/dotnet-cli-telemetry

I have added the opt-out environment variable via jj5-bin.

Create a desktop alias for an SMB mount on Mac OS X

Posted on by

So to create an alias to an SMB share on your Mac desktop:

First use Finder -> Go -> Connect to Server…

Enter a location such as: smb://server/share

Then use Finder -> Preferences… -> Show: Connected servers

The SMB mount should now be visible on the desktop. Right-click the share on the desktop and choose ‘Make Alias’. Then take connected servers out of your Finder preferences and rename the desktop alias probably as the name of the share.
