DietPi-Software | 7za command missing on current RPi image

[dietpi-user]

ADMIN EDIT

• This will be resolved automatically once DietPi is updated to v6.22.
• One can help testing the Beta which as well solved the issue: https://github.com/MichaIng/DietPi/issues/2632
• Or resolve on v6.21: G_AGI p7zip-full

Details:

• Date | Sun 10 Mar 19:00:54 CET 2019
• Bug report | N/A
• DietPi version | v6.21.1 (MichaIng/master)
• Img creator | DietPi Core Team
• Pre-image | Raspbian Lite
• SBC device | RPi 3 Model B+ (armv7l) (index=3)
• Kernel version | #1200 SMP Tue Feb 12 20:27:48 GMT 2019
• Distro | stretch (index=4)
• Command | 7za x -y 7.7z -offmpeg_rpi
• Exit code | 127
• Software title | DietPi-Software

Steps to reproduce:

Mode: Installing FFmpeg: audio & visual libary
[ OK ] DietPi-Software | Connection test: https://dietpi.com/downloads/binaries/rpi/ffmpeg_rpi.7z
[ OK ] DietPi-Software | wget https://dietpi.com/downloads/binaries/rpi/ffmpeg_rpi.7z -O 7.7z
[FAILED] DietPi-Software | 7za x -y 7.7z -offmpeg_rpi

Also, I've added the following to dietpi.txt by the way (maybe ffmpeg is required by home assistant?):

AUTO_SETUP_AUTOMATED=1

AUTO_SETUP_INSTALL_SOFTWARE_ID=0 # Open SSH
AUTO_SETUP_INSTALL_SOFTWARE_ID=136 # Motion Eye - web interface & surveillance for your camera
AUTO_SETUP_INSTALL_SOFTWARE_ID=73 # Fail2Ban - prevents brute-force attacks with ip ban
AUTO_SETUP_INSTALL_SOFTWARE_ID=157 # Home Assistant - open-source home automation platform

tail -f /tmp/dietpi-firstrun-setup.log

Expected behaviour:

Installation of the ffmpeg library, with extraction of 7z file with 7za. However the command 7za is not available.

Actual behaviour:

Constant retries by dietpi-software on first login in the background to try and install the ffmpeg library (which fails everytime).

Extra details:

I've managed to work around this issue by logging into ssh and running the following command:

sudo apt-get install p7zip-full

(p7zip was installed already, but this does not contain 7za)

Then dietpi-software is able to finish successfully.

Additional logs:

Log file contents:
/DietPi/dietpi/func/dietpi-globals: line 1373: 7za: command not found

@dietpi-user
Many thanks for your report.

Very strange, we did remove 7za just with the 2 minutes ago released v6.22 Beta, but it is a core dependency of DietPi prior to that. (On v6.22 we use 7zr as lightweight alternative instead).

Please verify this is installed:
dpkg -l | grep 'p7zip-full'

Otherwise install the related package:
G_AGI p7zip-full

Or apply the just now released beta, which does not use 7za anymore: https://github.com/MichaIng/DietPi/issues/2632

Okay thank you Michalng for your quick reply, no I don't think p7zip-full was present before I ran the apt-get install p7zip-full command.

It is installed now too:
ii p7zip-full 16.02+dfsg-3+deb9u1 armhf 7z and 7za file archivers with high compression ratio

But just fyi, I downloaded the following image today, below the contents from the hash.txt file. With a previous image I didn't have these issues by the way (MD5 : aac641f4c233ba0d3c6987478602f960, Modified Time : 31/01/2019 14:44:55), but then I didn't modify the dietpi.txt file neither.

@dietpi-user
Omg now that you mention it, yeah I know how the issue occurred. I used the new DietPi-PREP script that only installs p7zip (but not p7zip-full) according to v6.22 changes, but the DietPi version is still v6.22.

Damn mistake, however easy to fix and v6.22 will be released soon which will resolve this issue with the image as well.

[MichaIng]

v6.22 was just released, so the image should work now out of the box without above error.
