forcing oft mime type file to download
Apache is sometimes nice and sometimes ugly. Show me the ugly Apache 🙂
I have a webserver with Apache and some files doc, pdf and “oft” outlook template file.
Internet Explorer open “oft” directly without prompting and show the source code of the file.
add to your apache2.conf file following
AddType application/octet-stream .oft oft
Check your apache conf file that is allowed to use htaccess file
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
we need two mods, rewrite and headers, very often rewrite is enable, headers not so often. When you not have enable headers you will get a 500 server error from Apache.
enable headers with
a2enmod headers
apachectl restart
place your .htaccess file in your www data folder /var/www/
You need following content, this works with all other extension that you will be force to download
<FilesMatch “\.(.oft|OFT)$”>
ForceType application/octet-stream
Header set Content-Disposition attachment
</FilesMatch>
That´s it

Deployment with IExpress: How to turn your MSI file into an EXE
I have no problem with MSI file downloads. They are as simple as running an EXE. However, for reasons unknown, a lot of people don’t seem to like or understand downloading and running an MSI file; they feel more comfortable with EXEs. Visual Studio Setup projects turn your application into an MSI and a setup.exe file, which is inconvenient for distribution as generally online we want to provide the user with a single file download. Luckily there is a simple and free solution at hand in the guise of a quirky and little-known application included even as late as the Windows 7 base distribution called IExpress. This tool was originally created to enable branded deployments of Internet Explorer 6 (shocking, I know), but we can subvert it quite easily to our needs.

Can’t locate Debian/AdduserCommon.pm in @INC (you may need to install the Debian::AdduserCommon module)
Ubuntu 16.04 is sometimes wtf.
How to escape this crazy error?
Preconfiguring packages …
Setting up systemd (229-4ubuntu21.1) …
Can’t locate Debian/AdduserCommon.pm in @INC (you may need to install the Debian::AdduserCommon module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at /usr/sbin/addgroup line 34.

Use apt-file search AdduserCommon.pm on another Ubuntu VM. APT-File install separately on the maschine. So you can look which packet the file belongs to.
apt-file search AdduserCommon.pm
adduser: /usr/share/perl5/Debian/AdduserCommon.pm
now we reinstall the package adduser
apt-get –reinstall install adduser
Antoher way is copy the whole folder /usr/share/perl5/ from the working vm to the broken vm.
