I installed wine and iTunes. When I run iTunes application starts but it is unusable since I only get black screen. See photo. What to do here?
I had many cron jobs working perfectly before upgrade from Ubuntu 16.04 to 18.04. After the upgrade I can run all the defined jobs (using crontab -e) either in terminal or by clicking "Run Selected Task" in GUI "Configure Scheduled Tasks" but all these jobs are not being executed at scheduled (or any other) times... To say once again, I can perfectly without any problem execute all the defined jobs (call to R scripts) using terminal or mentioned GUI.
Output of cat /var/log/syslog | grep cron :

... (more of the LIST lines)
How to make cron jobs run at defined times?

EDIT 2:
I created jobs using command $crontab -e which opens /tmp/crontab.Rnzw6Y/crontab. The contents looks like this (several of those jut calling R scripts at different times/days).
45 15 * * 1-5 /usr/bin/R --vanilla --quiet < /home/username/code/scripts/R_script_1.R 2>&1 | tee -a "/home/username/log/R_script_1.R - `date +\%Y-\%m-\%d\ \%H:\%M:\%S`.log.txt" # JOB_ID_26
Let me point out that running this in terminal works just fine:
/usr/bin/R --vanilla --quiet < /home/username/code/scripts/R_script_1.R 2>&1 | tee -a "/home/username/log/R_script_1.R - `date +\%Y-\%m-\%d\ \%H:\%M:\%S`.log.txt"
All this worked perfectly fine until upgrade from 16.04 to 18.04.
I am not able to upgrade Ubuntu 16.04 to 17.10 due to issues with packages which I installed from LP-PPA-ubuntu-toolchain-r-test. These packages are numerous... Is there a way (using some tool or script) that automatically downgrades packages that are newer than official Ubuntu release?
I have two files in a folder on my Ubuntu 16.04:
a1.dat
b1.DAT
I want to rename b1.DAT to b1.dat so I would have following files as a result in the folder:
a1.dat
b1.dat
I tried (unsuccessfully):
$ rename *.DAT *.dat
Bareword "b1" not allowed while "strict subs" in use at (user-supplied code).
Bareword "DAT" not allowed while "strict subs" in use at (user-supplied code).
and
$ find . -iname "*.DAT" -exec rename DAT dat '{}' \;
Bareword "DAT" not allowed while "strict subs" in use at (user-supplied code).
Bareword "DAT" not allowed while "strict subs" in use at (user-supplied code).
Searching for this resulted in no meaningful solution...
On my Ubuntu 16.04 (guest system, VirtualBox) something is clogging up my disk lately. To the point of only 126 MB space left. It happened now for three days in a row. I delete 2 GB or more files to make space. After a few hours space is gone and I have no clue what is causing it...
The only thing that comes to mind is that I was trying to install .Net 4.5 (and other versions) in Wine unsuccessfully many times in past few days and maybe there are some files being left somewhere (where?)...
Any ideas on what and how to look for highly appreciated. Thanks.
I am looking for simple converter from mp3 to txt. I have tried, without success: julius, CMU Sphinx, ... In the past 4 hours I did not find a way how to use them (or properly install them).
What I am looking for is something like:
$ converterapp -infile myspeech.mp3 -outfile myspeech.txt
I am also fine with GUI application since I only have a few files to convert and can click around.
Edit: With the help of this answer Speech-recognition app to convert MP3 to text? I manged to get it working but it produces no output. Well, actually it produces a couple of blank lines (no words detected)...
