Get the error: /usr/bin/env: ‘python’: No such file or directory
Closed this issue · 7 comments
After doing all steps you indicated to install on ./netcheck.sh I get the following error:
SpeedTest-CLI: Installed
Logging to: log/connection.log
************ Monitoring started at: Di 18 Apr 2023 16:47:39 CEST ************
CONNECTED LINK SPEED:
/usr/bin/env: ‘python’: No such file or directory
Then script hangs.
I'm using Ubuntu Jammy
Any idea?
Thanks, Klaus
If you don't want to edit scripts, install the python-is-python3 package - that sets up the redirection of 'python' to the 'python3' that's all that recent versions of Ubuntu have.
Thank you very much, that fixed the error message.
Nevertheless, I still have a problem, and I apologise if it is just a problem of understanding on my part.
When I start the script as a service, I get the following one-time output in the log file, which does not change any more:
$ cat log/connection.log

This is certainly not intended and I conclude that the script does not do what it should.
"sudo systemctl status netcheck" results in the following output:
$ sudo systemctl status netcheck

Where can I find the config file?
Environment variable LDMHOME is set, ping and traceroute are installed.
What could be wrong?
Thanks in advice, Klaus
What config file are you referring too? Netcheck has no config file, it uses parameters when invoked. If netcheck is working as expected when you manually run it, I would suggest you follow a guide to setup a service on your system and start debugging it that way.
Config file is mentioned here: https://docs.unidata.ucar.edu/ldm/man/netcheck.html#NAME
Hi Klaus, I am the author of netcheck, but I have no idea what that website is. All documentation is retained in this repository.
I give up, obviously I am not smart enough to get the script to run
That website is talking about a completely different script with the same name (and presumably similar purpose) written in Perl.
This script is written in Python, and by default when run from the command line, it prints / logs something like what you've said or what I get if I try it now:
`me@pc:~/netcheck$ ./netcheck.sh
SpeedTest-CLI: Installed
Logging to: log/connection.log

`
It will then print / log nothing else unless or until it thinks the network is down when it does one of its checks.
It will then print that and, if and when the network comes back up, print that along with how long it thinks the outage is.
In short, if it produces more output than that, it thinks there's been a problem.
