Ubuntu HowTo: How to remove Python3.8 and Install Python3.6 as default Python in Ubuntu 20.04

Original Source Link

completely new here, I was working around from last 2 days to remove the python3.8 from ubuntu 20.04 and install python3.6 as default python. But the issue is when I tried to uninstall or purge python3.8 it removes everything such as all the packages and display drivers and CUDA etc.

How to do that, Is there any way ?

I would suggest not to remove the installed Python 3.8, as maybe it is used for system tools.

I’d suggest to add the deadsnake-ppa then you can install all common Python versions in parallel.

Ubuntu HowTo: Can’t Uninstall “asciidoc” Package

Original Source Link

I was building from source a package which needed asciidoc on Ubuntu 19.10. Now I want to uninstall it but I get the following

Package 'asciidoc' is not installed, so not removed

while it is clearly installed. Why is that happening? How can I uninstall it?

The main asciidoc executable in 18.04 LTS and newer versions is located in asciidoc-base package.

You have to remove it:

sudo apt-get purge asciidoc-base

For source code installations, here are the install/uninstall commands…

Installing asciidoc for all users

Create configure using autoconf(1); use configure to create the Makefile; run make(1); build the man pages; install:

$ autoconf
$ ./configure
$ make
$ sudo make install

To uninstall:

$ sudo make uninstall

Source: http://asciidoc.org/INSTALL.html

Update #1

For binary installations…

dpkg -l *ascii* | grep ii

un asciidoc <none> <none> (no description available) 
ii asciidoc-base 8.6.10-3 all Minimal version of asciidoc not suitable for pdf 
ii asciidoc-common 8.6.10-3 all Basic data and configuration files for asciidoc un asciidoc-doc <none> <none> (no description available)

To completely uninstall asciidoc, you’ll need to run all of these commands…

sudo apt-get purge asciidoc # already done

sudo apt-get purge asciidoc-base

sudo apt-get purge asciidoc-common

Server Bug Fix: Did aptitude uninstall the gnome gui?

Original Source Link

Recently I wanted to remove the keyboard-configuration app for linux, so I typed

sudo apt-get remove keyboard-configuration 

it prompted me if I wanted to remove a bunch of packages (17 MB), and now knowing the inner working of Debian, I complied. Next time I went to reboot the machine, it no longer boots to the os gui. Instead I get booted to a shell interface. Please see this image:

Shell interface that my machine now boots to

How would I troubleshoot to find the cause? And how would I fix it? The distribution is Debian.

EDIT: according to the apt log, the following was removed:

packages that were removed

Do the following:

$ sudo apt-get install xserver-xorg

and then reboot. That should do it. You removed the Xorg server, that’s why you cannot boot into the GUI.

Server Bug Fix: Uninstall Ruby on Rails on CentOS 6

Original Source Link

How can I remove Ruby on Rails and all associated gems?

I tried yum remove ruby but get this response:

yum remove ruby
Loaded plugins: fastestmirror, security
Setting up Remove Process
No Match for argument: ruby
Loading mirror speeds from cached hostfile
 * base: mirror01.th.ifl.net
 * extras: mirror01.th.ifl.net
 * updates: mirror01.th.ifl.net
No Packages marked for removal

If I write $rails -v, $ruby -v or $gem -v I still get their versions returned to me, which indicates that they’re installed.

try the following,

# yum provides ruby

or

# rpm -qa | grep -i ruby

This will display the RPMs that is currently installed that provides the ruby binary.

Once you have the name of the rpm you can then run the follow to remove the RPM from your system

# yum erase <package_name>

It might be possible that

  1. the ruby rpm was installed with a custom named rpm package
  2. that ruby was compiled with gcc on the current host

If so, then you will need to manually remove ruby libs and binaries from your system path.

You can locate binary by

# which ruby 

Then you can proceed to remove it from your path.

Else search with find

# find / -name "*ruby*"

then proceed to remove the directories from you server.

I guess below command would be useful for you to uninstall RVM packages. Please execute one by one.

Commands:

  1. rvm list

    (it will give you what ruby packages are presently installed on your server)

  2. rvm remove ruby_pkg_name

then once successfully executed above commands then check whether ruby uninstalls or not like ruby -v, gem -v, rails -v or which ruby

hope this will helpful for you!

removing ruby from the server i.e CentOs depends upon how you have installed it.
If it was install directly without rvm or rbenv then

yum remove ruby

or

   sudo yum remove ruby 

if it is installed using rvm

rvm remove 1.9.3-p551

or

 rvm remove <ruby-version>

if its is installed using rbenv
like:

rbenv uninstall 2.1.0

or

rbenv uninstall <ruby-version>

Server Bug Fix: Silent unattended uninstall switches for vmtools?

Original Source Link

Looking for the NON-MSIEXEC totally silent uninstall switches for vmtools.

I know the silent install is VMware-tools–x86_64.exe /s /v /qn
I just need the uninstall, I feel like it would be similar but it is nowhere to be found in all the land.

/? gets me a installation box, but does not include the removal information.

Thanks in advance 🙂

I was running into the same issue, trying to do an uninstall and reinstall for an automated server 2016 deploy that doesn’t configure the service correctly on the first install. This is what I came up with that seems to work for uninstalling. Running in powershell, but should be easily adaptable for your use case.

Start-Process "setup64.exe" -ArgumentList '/S /v "/qn REBOOT=R REMOVE=ALL"' -Wait

I adapted the script on this page to include this line for uninstall as the /c flag doesn’t seem to work correctly anymore.
