networks – network broken after the installation of KVM

I started going through the instructions about installing KVM without realizing that I was not doing SSH on my server and doing everything on my local machine. I have as fas as the installation of the following

sudo apt install qemu qemu-kvm libvirt-bin bridge-utils virt-manager

Y

sudo apt install netplan

After purging and deleting automatically, I have finished with a non-functional network.

lshw -c network 

shows my adapter as disabled. After ifconfig up enp3s0 it appears in the config but it still does not work. I have tried several configurations. The result is that /etc / network / interfaces is completely ignored by the system due to a parameter in NetworkManager.conf. When I put myself handled = false, the interface gets some strange ipv6 address, but not ipv4 in static and DHCP configurations. Configuration through GUI did not result in any significant results.

I would really appreciate any advice on this, because the only solution for me now is the complete reinstallation of the system, which is not really optimal in any way.

System installation: the post-execution installation script is not running

I have the postinstall script that I want to run after the previous installation. My pre-installation file does the installation, no problem. However, I can not run my postinstall script. I have tried some things, but I am sure that I have the wrong syntax. I tried using late_command_string, ubiquity / success_string. Here is my last attempt:

Chain d-1 preseed / late_command
in-target / usr / bin / wget -O /tmp/fca_postinstall.sh –tries = 2 http://10.64.42.74/fca_postinstall.sh;
in the destination chmod 750 /tmp/fca_postinstall.sh;
in-target / bin / bash /tmp/fca_postinstall.sh;

Can someone please point out what I'm doing wrong?

macbook pro – The installation of Trisquel can not see the internal SSD

I'm trying to run Trisquel, a completely free software distribution, on a MacbookPro 2017 with touch bar, I know a computer made by a company that is not so free of software support, but I really just made the entire change to free software only mentality after I had already bought the mac.

fdisk -l does not notice the internal ssd, an nvme unit, which has the macbook pro. This mac was made before the unpleasant chip "T2" came into play, which would have prevented this installation attempt completely. Other distributions of Linux, for example, the installation of Ubuntu, recognize the internal unit. Lspci shows that the unit does exist, but is "UNCLAIMED", which means that there is no driver to "reclaim" the unit, even though the Linux kernel has drivers for NVME, which I even verified, Trisquel as well.

Any idea why the installation can not see the disk? Any suggestions? Any help at all is appreciated.

Installation: The wrong version of Drush is installed when you try to install the site locally

I'm trying to install Drush 8.1.17 locally using the Drupals documentation itself (enter the description of the link here), but every time I try to install it, 9.2.6 is installed in its place. Worldwide, install the correct Drush but not the site locally for a specific project. Here is my intent:

Worldwide

SITE LOCALLY

Any reason why this is happening, or …?

Please guide me to the hosting service provider that supports the installation of pear packages.

I need to run a web application that needs the PEAR registration package, please guide the hosting service providers at a reasonable price.

The installation of Ubuntu restarts each time a manual network connection is configured

I do not install Ubuntu often. However, now I am having this problem twice.

The first time, I ignored it, I continued my installation with DHCP enabled, then I manually configured the network adapter after installation.

Now, I am in a completely different network, a completely different hardware, etc., and I am trying to do a basic installation of the Ubuntu 18.04 server again.

I reach the initial stages, the installation finds a DHCP address for the network adapter and gives me the possibility to reconfigure it at that moment. I edit the configuration and specify the network information I want to use for IPv4 after choosing "Manual" for the IPv4 Method:
enter the description of the image here

When I choose "Save" the configuration, the installation is immediately restarted on the first screen and the configuration is deleted.

This is the second time that I install Ubuntu 18.04 with the same problem in completely different networks and hardware. I'm 0 for 2 and I can not find a bit of this on the internet about this problem.

Why is this happening?

EDIT: I found this post unanswered: https://askubuntu.com/questions/1124742/ubuntu-18-04-2-lts-server-network-configuration-problem-during-setup?newreg=444bcbeb65ab498b92298f80ad9427dc

installation – What java JDK is compatible with oracle instant client 10g

I'm an internal stuck trying to recover data from Oracle 8i (a database that is how I am)

The problem:

I need to write a java script that extracts data from Oracle 8i to a newer server. The last client that is compatible with Oracle 8i is the Oracle 10g client (the 10g instant client is still available for free on the Oracle website).

Documentation is scarce about 10g client compatibility. My server does not currently have java installed and my question is what version of java is compatible with the 10g client?
