I have tried installing the elasticsearch package using apt on Ubuntu 14.04, but when I run
sudo service elasticsearch status, I get the following output:
* elasticsearch is not running
I tried running
sudo service elasticsearch start, and it claims to start OK.
However, no logs are recorded in /var/log/elasticsearch.
I tried running
sudo /usr/share/elasticsearch/bin/elasticsearch, and got the following output:
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. Exception in thread "main" java.lang.NoSuchFieldError: LUCENE_7_0_0 at org.elasticsearch.Version.<clinit>(Version.java:50) at org.elasticsearch.bootstrap.Bootstrap.<init>(Bootstrap.java:76) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:287) at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:159) at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:150) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:115) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92)
What could be causing this error?
The elasticsearch documentation does not seem to include information on how to install lucene or where to configure its installation.
This question is only for Trusty (14.04)… Here is what I have done to install php7.1-bcmath:
sudo add-apt-repository ppa:ondrej/php sudo apt update sudo apt install php7.1-bcmath
But I got the following result
E: Unable to locate package php7.1-bcmath
I assume this is because ppa:ondrej/php support ubuntu versions starting from 16.04 and upper.
Is there a way to circumvent this? Like copying a deb file and using dpkg (If yes, where is this file)?
FYI, here is the result of
apt-cache search php7 (very small isn’t it?)

I firstly installed Vim in my (L)Ubuntu 14.04 with sudo apt-get install vim After that, as required from a plugin I wanted to use, I upgraded to Vim 8.1 using the ppa:jonathonf/vim repository. Being disappointed by that plugin I wanted to try another one but it has a still unsolved bug in Vim 8.1, this is why I now need to downgrade to Vim 7.4. My idea is to completely uninstall Vim and then reinstall it (having already removed ppa:jonathonf/vim).
To do so I tried
sudo apt-get purge vim
sudo apt-get autoremove
a couple of times and now I get this:
user@computerName:~$ sudo apt-get purge vim [sudo] password for user: Reading package lists... Done Building dependency tree Reading state information... Done Package 'vim' is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
However, Vim is still there and I can use it. If I check for Vim version within Vim I get this:
:ve VIM - Vi IMproved 8.1 (2018 May 18, compiled May 15 2019 14:58:47)
Perhaps there is an easier way to downgrade a software in Linux? Or is my idea valid? Do you have any suggestion? Thank you!
PS: As advised by GiftZwergrapper:
user@computerName:~$ which vim /usr/bin/vim
I am migrating our software from Trusty to Bionic. On trusty, there were many dependencies which were manually installed, but many of those were removed/renamed in Xenial itself and not available on Bionic. For e.g.,
python-support etc. Is there any easy way to find the equivalent packages for these, on Bionic ? Or, will some of them have to built for Bionic if they are mandatory ?
The host system is an iMAC:
macOS Mojave Version 10.14.5 iMac (Retina 5K, 27-inch, Late 2015) Processor 4 GHz Intel Core i7 Memory 16 GB 1867 MHz DDR3 Graphics AMD Radeon R9 M395X 4 GB
Version: 6.08 r130520 (Qt5.6.3) VirtualBox 6.0.8 Oracle VM VirtualBox Extension Pack
The VM is painfully slow, when I click on the desktop in the VM I have several seconds before I see a response. Is there anything I can do to improve the performance. The host system is super quick.
Just “upgraded” from 14.04 to 16.04 and restarting doesn’t work. Also when I start from “hard”, I get booting twice. First about 8 sec. time followed immediately by another of some 26 sec. Very troublesome case. Tried to search for /ect/run/runleves/boot and rc*.d to no avail. May be the best way is to revert back to 14.04. Victor
Keep trying to install and have followed instructions but keep ketting the same error: enter image description here
I am running Ubuntu 14.04, and I need to upgrade glibc to at least version 2.21 to run Matlab 2018b. I have 2.19 version. I tried this solution but the candidates version am getting is just glibc 2.19. I can’t upgrade my ubuntu version because am running ROS along side with Matlab and it is supported on ubuntu 14.04
Any ideas!! Thanks
In ubuntu 14.04 the screen is continuously blinking before the startup and its taking more than 2 minutes for boot. This issue is persisting after upgrade and update.
Here i’m adding the picture of boot screen
I have no idea why this is happening my PC is dual boot with windows. Any assistance regarding this issue will be helpful.
As Ubuntu 14.04 is going to end for 32bit, should I install Ubuntu MATE over 14.04 using code sudo apt-get install ubuntu-mate-core ubuntu-mate-desktop in the terminal OR first remove Ubuntu 14.04 and fresh install Ubuntu MATE 18.04.2 LTS (Bionic) using its ISO image? Please suggest which way would be better as need to have a secure environment going ahead on my 32 bit Dell Inspiron which is working fine till date with dual boot.
