Script exit after opkg update

[hugoleosp]

Hi, I'm trying to install HA using this script and it exits right after opkg update.

Checking the script, the next line would be: opkg list | grep python3-base | head -n 1 | grep -Eo '\d+.\d+'

The result of this line is empty, and removing the last grep, it shows: python3-base - 3.10.9-1 - This package contains only the interpreter and the bare minimum for the interpreter to start.

I'm on Orange Pi custom firmware that I compiled myself: Model: Xunlong Orange Pi R1 Plus LTS Architecture: ARMv8 Processor rev 4 Target Platform: rockchip/armv8 Firmware Version: OpenWrt 22.03.2 r19803-9a599fee93 / LuCI openwrt-22.03 branch git-22.288.45147-96ec0cd Kernel Version: 5.10.146

Could you please help me understand what is wrong? Thank you =D

It's difficult to say without logs, but

echo 'python3-base - 3.10.9-1 - This package contains only the interpreter and the bare minimum for the interpreter to start.' | grep -Eo '\d+\.\d+'
3.10

works correctly and returns the python's version.

You may add set -x in the beginning of the file to track every executed command and find a real last command

You use a different command, not from the script. Note a backslash before the dot in the script in the latest version

You are right. But still my point is valid. Those regex won't work with GNU grep which returns null.

Busybox grep

root@OPIPlusLTS:~# opkg list | grep python3-base | head -n 1 | grep -Eo '\d+\.\d+'
3.9
root@OPIPlusLTS:~# opkg list | grep python3-base | head -n 1 | grep -Eo '[[:digit:]]+\.[[:digit:]]+'
3.9

GNU grep

root@OPIPlusLTS:~# opkg list | grep python3-base | head -n 1 | grep -Eo '\d+\.\d+'
root@OPIPlusLTS:~# opkg list | grep python3-base | head -n 1 | grep -Eo '[[:digit:]]+\.[[:digit:]]+'
3.9
root@OPIPlusLTS:~# grep --version
grep (GNU grep) 3.6

Oh, you mean that you have a command that works with both gnu and busybox. That's fine, can you please create a PR to fix that?

@hugoleosp Script works. opkg install python3-pip-src is needed for openwrt 22.03 branch.
