Commands can't call child commands

nickDW · September 22, 2017, 9:58pm

Hello everyone.

Ever since I upgraded to LEAP42.3, I have had issues installing software.
My zypper would be unable to use rpm. (yes I used sudo).
I found a workaround for this with the ‘su -’ command, to simulate an actual login, thinking i needed to fix my rpm.

Now i tried to unpack a .tar.bz2 file (hoping to re-install rpm that way), but my command failed. The tar command could not call the bzip

Below you’ll find the code i had issues with. For testing purposes I will use neovim.

As regular user with sudo access:

$ sudo zypper install neovim

trying to extract rpm tar.bz2 as user with sudo access:

$ sudo tar xvfj ~/Downloads/general/rpm-4.13.0.1.tar.bz2 -C /opt
tar (child): bzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

What could be causing this? How can I fix it?

I_A · September 22, 2017, 10:17pm

what you are saying is zypper does not work when called with sudo (because rpm can not be found) but works with su -?
can you run rpm as an ordinary user just do

rpm

if not check and see what the $PATH variable is just do

echo $PATH

I’m not sure where you got that bzip archive but I’m reasonably sure the cause of the error is that /opt does not exist on your system and don’t do that that won’t fix anything

if rpm can be run by an ordinary user and you said it was an upgraded system tell us the output of (if you upgraded from 42.2)

rpm -qa --queryformat "%{Name}:%{Distribution}
" | grep -F "42.2"

I have been able to extract files with the tar command to /opt in the past, as you can see in my $PATH variable. I’m not entirely sure it’s the right place to store those programs (for all users) tho.

I_A · September 22, 2017, 10:55pm

as rpm works there is no need for it’s replacement
my best guess is one of the folders in your $PATH is misconfigured check if all exist
I’d suggest creating a new test user and see if the issue exists with a clean profile
you didn’t say from what OS and how you did the upgrade

rpm -qa --queryformat "%{Name}:%{Distribution}
" | grep -F "42.2

is if you did from 42.2

nickDW · September 22, 2017, 11:03pm

I upgraded from 42.2 to 42.3 following this guide: https://en.opensuse.org/SDB:System_upgrade

nickDW · September 22, 2017, 11:50pm

When creating a new user, test, who has sudo access, i got this after logging in directly with the test account:

I think this confirms the issue.
