Disable multipath while installing ubuntu - linux

I have some problem while installing any ubuntu based distro
I have following setup
1 SSD drive with Windows
2 * 500 Gb drives ( same manufacturer etc.)
Whenever I try to install any ubuntu based distro, those 2 disks are detected as Mutlipath
(/dev/mapper). I can't install anything, as one of those disks is empty , one has some important data and stuff. When I disconnect one drive , then ubuntu setup sees it coretly and I can install linux without any problem. If I reconnect drive, linux fails to start ( multipath is loaded and it fails to find linux files )
Tried to plug in one drive into other slots on MB but still detected as multipath.
I even tried to install multipath-tools ( using terminal sudo apt-get install multipath-tools ) then in setup I was able to see all partitions on my drives , but disk were listed twice, once as /dev/mapper and once as /dev/sdb . Any attempt to install ( either on mapper or sdb ) resulted in some strange errors ( once it was failed to create swap on mapper , another time I just got "????" in message window
Any help, on how to disable this multipath and allowing to install ubuntu based distros would be welcome :)
UPDATE: It's clearly ubuntu installer issue. I just installed debian on same configuration without any problems. Hovever I'd prefer ubuntu , as it's more user friendly and less problems with dirvers etc.

To disable multipath:
multipath -f <path>
as per: http://docs.oracle.com/cd/E19122-01/j4500.array/820-3163/bcghjife.html#bcgcabjj

Any success installing VMware Workstation on virgin Rocky Linux 8.5?

Using a virgin (but updated) version of Rocky Linux 8.5, I am trying to install VMware Workstation 16.2.1 (and others), but get compile errors during the first attempt to run, when vmmon and vmnet are being built.
All the proper, current headers from kernel-devel and kernel-headers are installed.
I tried upgrading to the 5.16.4 kernal at kernel.org, with all associated headers, and basically get the same errors.
"Unable to install all modules." i.e., vmmon and vmnet
Posts i have found with searching the net seem to indicate that there was a "back-port" of an upstream fix to Rocky that has affected the ability to build the loadable kernel modules necessary to run vmware - but i cannot confirm this is actually the problem that I am experiencing.
So i simply ask these questions: Can anyone (today) install VMware Workstation 16.2.1 (or any version), on a fresh install of Rocky Linux 8.5?
If so, would you please point me at your installation instructions, because I am unable to build "vmmon" and "vmnet" modules today (2022-01-04), that allow me to actually run virtual machines with vmware? (The kernel modules fail to compile and build.)
(and after 15 years of using stackoverflow i do not have the reputation to create a "rocky-linux" question tag...)
See https://unix.stackexchange.com/questions/689436/the-vmmon-and-vmnet-vmware-workstation-kernel-modules-fail-to-build-on-rocky-lin
mbubecek's instructions work for a variety of releases and should compile perfectly and run without issue, if you follow his instructions.
I have successfully used these methods at least a half dozen times with Rocky 8.5 and 8.6 with vmware workstation 16.1 up to version 16.2.1
NOTE: This error is NOT Rocky Linux specific. Also happens on some versions of RHEL 8 and CentOS 8.x I would also expect this "fix" to work on all of the other linux versions that are RHEL 8-derived.
I've been having difficulty with the same issue, and a colleague pointed me to check my kernel. This is our "official" resolution. See if the below works for you.
This is due to differences between the kernel and the source code for the VMWare modules, see here for more information. You can get the correct kernel modules, and build them by executing the following commands
wget https://github.com/mkubecek/vmware-host-modules/archive/workstation-16.1.0.tar.gz
tar -xf workstation-16.1.0.tar.gz
cd vmware-host-modules-workstation-16.1.0/
make
sudo make install
If you get the error,
crosspage.c:53:16: fatal error: linux/frame.h: No such file or directory
The error is described here. The solution is to remove (i.e. comment out) the offending include file in crosspage.c After doing the sudo make install, it is a very good idea to restart you host.
You may need to manually insert the modules into the kernel the first time after running make install'. The kernel modules (vmmon.ko and vmnet.ko) will be found at /lib/modules//misc. The following set of command will do this:
cd /lib/modules/$(uname -r)/misc
sudo insmod vmmon.ko
sudo insmod vmnet.ko
The modules should be load automatically after a restart/reboot.
If you update vmware to a different version (say 16.2.1) you may need to this again. Just change the versions in the above commands. If you hit the update button on the splash-screen and failed to notice the version you are updating to, you can run `vmware -v' at a command prompt to get the version you updated to.

Can not log in Elementary after install ubuntu 18.04 (dual boot)

I am new to Ubuntu 18.04. It has been a long time that I have not updated anything new on my current OS which is Loki (interestingly, besides Loki does not allow ppl to upgrade Juno).
For some reasons, I have to install another Linux OS on my machine, which is ubuntu 18.04 - the minimal installation. Although everything works perfectly to Ubuntu, it makes me cannot log in to my main OS.
Description of an issue: After selecting a boot of elementary, I log in my account on a log-in page of Elementary. It does not show anything else and move back to the log-in. Another try with a guest account (with no password), still the same problem.
Because most of my data and work in Elementary, I have to find a way to solve this problem. Is there anyone here giving me a hand? Thank you very much.
I ran into same problem once.
Login into tty mode by Ctrl+Shift+F1,and enter:
sudo dpkg --configure -a
sudo apt-get install ecryptfs-utils
sudo reboot
And I was able to login
Trying tty mode by Ctrl+Shift+F1, I was able to log-in in a terminal. Turn out that the Ubuntu has used almost the left memory to load an OS. By removing some files by the command rm -rf [filename] to release around 2GB, I was able to have everything back. It was freaking for a while. Phewww...

my linux suse 13.6.2 is missing a directory

I downloaded Suse Linux 32bit 3.16.6.2.0 as an iso, burned a DVD and installed it as a dual OS with my Win 7. Now, to get the WLan Stick to work....
Using the Win OS I downloaded two files :
ndiswrapper-1.59.tar.gz and fwlanusb-1.00.00.tar.gz
I moved them into the Linux partition and ran the ./install files as instructed.
With both of these installation it requires running a makefile script. In both cases it comes to a crashing stop when /lib/modules/kernel3.16.6.2.0/build is not found.
The 'build' subdirectiory or file is not present. Can I call up one of the rpms to get this part of the Linux OS installed?? Which rpm??
Solving the problem with my WLAN Stick is especially hard because often the Linux documentation says : "in order to make you your internet connection function you must download xyz".
Please install the kernel-source RPM for your running kernel. If this doesn't help already, please make sure that a symlink from /lib/modules/kernel3.16.6.2.0/build to /usr/src/linux exists.

How to set up Virtualbox 1366x768 resolution for a Linux guest?

I have been trying maybe weeks now to figure out how to configure VirtualBox to have 1366x768 resolution on a linux guest, which is on a windows 8.1 host.
My configuration:
Windows 8.1 as host
Linuxmint 17.1 as guest (tried ubuntu and debian too but no luck)
Virtualbox 4.3.26 and its extension pack
Laptop is powerful with 16GB ram and 4GB Nvdia
My problem is that it doesn't matter what I used, nothing worked.
Please do not post the answers on most known websites, I tried them already.
Once your VM is started, you need to run the VBox Linux Guest Additions.
First try to run it from the VirtualBox window's menu:
Devices >> Insert guest Additions CD image...
and follow the instructions.
If that fails, open a terminal and go to the directory where you CD reader is mounted (/run/media/ on Fedora or /media/ on Ubuntu for example).
Then type command sudo ./VBoxLinuxAdditions.run
Complete instructions can be found on the VirtualBox user manual
Once Guest Additions are installed, reboot your virtual machine. You should be able to resize your screen to your heart's content.
I installed the new VirtualBox 5.0.0_BETA2 and it solved my all problems. Great product is getting ready! Cant wait the latest release. more than a PERFECT software. Now you can remove top bar and/or bottom bar easily. Show what you need.
If you are having problem like me with 1366x768 I recommend you to install latest versin of VB even if it is Beta!

zfs installation issue Ubuntu 12.04 on Amazon EC2

I attached Three EBS Volumes of 3GB to an Amazon EC2 Micro-instance and mounted the disks xvdd, xvdc and xvdb.
My aim was to create a zfs pool using these 3 disks.
I had updated, upgraded Ubuntu 12.04, installed the zfs-linux dependencies, added the zfs-native repo PPA and then issued the zfs install command whhich is
sudo apt-get install ubuntu-zfs
After this, I get the console status which is as below and after the "run-parts:" status indicated below, the install process never proceeded further. I waited for 20+ minutes and got this:
Setting up zfs-dkms (0.6.0.91-0ubuntu1~precise1) ...
Loading new zfs-0.6.0.91 DKMS files...
First Installation: checking all kernels...
Building only for 3.2.0-31-virtual
Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.
Setting up linux-headers-3.2.0-35 (3.2.0-35.55) ...
Setting up linux-headers-3.2.0-35-generic (3.2.0-35.55) ...
Examining /etc/kernel/header_postinst.d.
run-parts: executing /etc/kernel/header_postinst.d/dkms 3.2.0-35-generic /boot/vmlinuz-3.2.0-35-generic
Is this issue related to EC2 kernel for Ubuntu? or does the machine to run ZFS should be of higher capacity?
Usually with hosting providers the kernel is the case. My provider (ovh) delivers their own customized (and allegedly more secure) kernel (alas without sources), although reluctantly permits installing the generic kernel, which solved the problem for me. I don't know about Amazon - perhaps their customized kernel is crucial for their EC2 service. On the other hand I very much doubt any hosting provider would produce the source code of their kernel.
