I have a fresh 20.04.1 Ubuntu and I want to install Emacs 27. The standard emacs from apt-get is 26.3, so I want to install it via ppa.

So I run software-properties-gtk, go to other software and add ppa:kelleyk/emacs. A pop-up appears asking me to update the package sources, I confirm. Now I try to install it:

$ sudo apt-get install emacs27

I just installed python3.7 on my 18.04LTS via the deadsnakes ppa:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.7 -y

Now I want to create a virtual environment with python3.7 -m venv env but I get

Error: Command '['/path/to/desired/env/bin/python3.7', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

python3 -m venv env0 worked fine before.

Why does this happen?
What can I do to create a virtual environment for python3.7 on Ubuntu 18.04LTS?

I did sudo mv /tmp /var/lib/apt/lists not realizing that it would move the whole folder and not just the contents.

I since do (as suggested in Accidentally deleted tmp folder)

sudo mkdir -m 1777 /tmp

on startup, but after a while it disappears again. What can I do? how can I debug this?

It seems that /tmp is renamed to /snapshot.0 (or with a higher index if other snapshots already exist).

Restart does not solve it. But shutting down without a /tmp isn't a problem either, on startup a new /tmp is there. However within 4 minutes it is renamed to another snapshot.

What happens without /tmp:

  • no tab completion in bash (sometimes)
  • programs such as chromium-browser and system monitor don't start
  • apt-get seems to rely on /tmp as well

I currently execute sudo mv /snapshot.0 /tmp whenever /tmp disappears.

Experiments:

I start the computer(as we will see /tmp is still there apparently it survived restart) and open a terminal where I execute:

$ while true; do 
   t=$(date +%H:%M:%S);      #timestamp as hour minute seconds
   date;ls -lt / | head -3;  print out date and most recent folders in /
   ls -l /tmp        > ~/Desktop/ls.tmp.log.${t}; 
   ls -l /snapshot.0 > ~/Desktop/ls.snap.log.${t}; 
   sleep 60; 
done;

I do nothing else! log in terminal:

ls: cannot access '/tmp': No such file or directory

So within 5 minutes /tmp has been renamed to /snapshot.0.

there is no difference between ls.tmp.log.19:4[4-8]:12 There is also no difference between ls.tmp.log.19:48:12 and ls.snap.log.19:49:13 so it can't be the content of /tmp.

Progress:

While I was hoping for a solution that makes things as they were before(without reinstalling the system) Giorgos Saridakis' suggestion of symlinks does work helps a lot. However I still can't start system monitor:

$ gnome-system-monitor 
cannot create temporary directory for the root file system: Permission denied

despite having all permissions set:

$ ls -lt /

drwxrwxrwt   8 root root       4096 Jun 27 15:21 snapshot.0

...
lrwxrwxrwx   1 root root         11 Jun 23 22:12 tmp -> /snapshot.0

I guess I'll have to write a demon after all...

I wrote a script:

#!/bin/bash
while true;
do
    if [ ! -d "/tmp" ];
    then mv /snapshot.0  /tmp 2>> /home/t/tmp.rename.bg.err;
     date >> /home/t/tmp.rename.bg.log;
    fi;
    sleep 10;
done

that is executed with

sudo bash tmp.rename.sh &

after login. It's not ideal but I don't have to get into writing daemons just yet.

I don't remember installing anything recently but when I pulled my laptop out of standby today I got the following notification:

enter image description here

In words: An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: Error: Opening the cache (E:Couldn't create temporary file to work with /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu__dists__bionic__InRelease - mkstemp (2: No such file or directory), E:The package lists or status file could not be parsed or opened.)'. This usually means that your installed packages have unmet dependencies (Side question: Is there a log file somewhere to copy the text from?)

I don't know what the right-click menu is. When I click on preferences, Software & Updates opens up, but I'm unsure what to do there.

running apt-get check diplays

Reading package lists... Error! E: Couldn't create temporary file to work with /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_bionic_InRelease - mkstemp (2: No such file or directory) E: The package lists or status file could not be parsed or opened.

I have since tried: per https://sillycodes.com/quick-tip-couldnt-create-temporary-file/:

sudo apt-get clean sudo mv /var/lib/apt/lists /tmp sudo mkdir -p /var/lib/apt/lists/partial sudo apt-get clean sudo apt-get update reverted with sudo mv /tmp /var/lib/apt/lists

There were error messages for several repositories, examplary: W: GPG error: http://de.archive.ubuntu.com/ubuntu bionic-backports InRelease: Couldn't create temporary file /tmp/apt.conf.tiVq7R for passing config to apt-key E: The repository 'http://de.archive.ubuntu.com/ubuntu bionic-backports InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I want to install ubuntu as a virtual machine on my ubuntu machine. The version of the host system is: Ubuntu 18.04.4 LTS The iso I want to install is: ubuntu-18.04.4-desktop-amd64.iso So I downloaded vmplayer and ran:

sudo bash VMware-Player-15.5.1-15018445.x86_64.bundle

When I run vmplayer in terminal, I get 

[AppLoader] Use shipped Linux kernel AIO access library.
An up-to-date "libaio" or "libaio1" package from your system is preferred.

I select "Create new virtual machine", fill everything out, choose /home/me/vmware/Ubuntu 64-bit as location. I choose 10GB disk capacity and "Store virtual disk as a single file".

there is more output on the terminal:

In Xournal++ I want to use Tools -> Add/Edit Tex But I get

Could not find kpsewhich in PATH; please install kpsewhich and put it on path.

I checked, it is installed

$ whereis kpsewhich
kpsewhich: /usr/bin/kpsewhich /usr/share/man/man1/kpsewhich.1.gz

But on

$ PATH=$PATH:/usr/bin/kpsewhich:/usr/share/man/man1/kpsewhich.1.gz
$ xournalpp

I still get the error message above.

UPDATES:
I checked echo $PATH and /usr/bin is already on the path.

I want to execute a script that starts with

library(dplyr)  
library(lubridate)  
library(ggplot2)

I started out with regular r-base-core and r-cran-lubridate installed. I got:

Error in mutate_impl(.data, dots) : 
  Evaluation error: `as_dictionary()` is defunct as of rlang 0.3.0.
Please use `as_data_pronoun()` instead.

(the code itself doesn't use mutate_impl it seems to be this issue https://github.com/r-lib/rlang/issues/674, suggesting an update of dplyr

r version was R version 3.4.4 (2018-03-15) for dplyr I didn't know how to find out.

So I changed the source as described elsewhere: added deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/ to /etc/apt/sources.list

sudo apt-get update
sudo apt-get install r-base
sudo apt-get install r-cran-dplyr

I use 2 keyboard layouts de1 and de2. Regularly, I try out d2 and close the lid. Upon reopening I need to log in again but I can only do so via de2. I can click on the little indicator to switch between de1 and de2 but the layout stays the same (I can tell from the dead keys). I can also click on "switch user" which opens up the regular log in screen. There I can change the layout but entering the password only brings me back to the other login screen again.

I installed pycodestyle via pip3

pip3 install pycodestyle

But then the example goes 

pycodestyle --first optparse.py

And my bash doesn't find pycodestyle. I can find the exact path with 

pip3 install --upgrade pycodestyle

which returns Requirement already up-to-date: pycodestyle in /home/user2740/.local/lib/python3.6/site-packages and then do 

python3 /home/user2740/.local/lib/python3.6/site-packages/pycodestyle.py --first optparse.py

And I guess I could do an alias, but is there a way to have this happen automatically?

I have a server server.name. With a folder /home/user229472/folder

I can use ssh like this:

ssh [email protected]
cd folder
...

scp works as well:

scp [email protected]:folder/file.txt .

But I cannot ssh directly into folder:

ssh [email protected]:folder
ssh: Could not resolve hostname server.name:folder: Name or service not known

I've tried lots of variations but none works:

 ssh [email protected]:22
 ssh [email protected]/
 ssh [email protected]/home/
 ssh [email protected]/home/user229472
 ssh [email protected]:/home
 ssh [email protected]:/home/
 ssh [email protected]:/home/user229472/folder
 ssh [email protected]:/folder
 ssh [email protected]:folder
