v1.5-beta (package from download link: libreqos_1.5.202406251802-1_amd64.deb for ubuntu22.04 - libpython3.10, build_dpkg.sh got some missed/broken check or no dependancy check,

[interduo]

I installed a libreqos for testing purposes using download link from form and deb package libreqos_1.5.202406251802-1_amd64.deb.

After instalation I tried to run:

root@libreqos-beta:/opt/libreqos/src/bin# ./lqosd 
./lqosd: error while loading shared libraries: libpython3.10.so.1.0: cannot open shared object file: No such file or directory

Simply check:

root@libreqos-beta:/opt/libreqos/src/bin# ldd lqosd
    linux-vdso.so.1 (0x00007ffff63e1000)
    libelf.so.1 => /lib/x86_64-linux-gnu/libelf.so.1 (0x0000712a26b67000)
    libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x0000712a26b4b000)
    libssl.so.3 => /lib/x86_64-linux-gnu/libssl.so.3 (0x0000712a26aa1000)
    libcrypto.so.3 => /lib/x86_64-linux-gnu/libcrypto.so.3 (0x0000712a25a00000)
    libpython3.10.so.1.0 => not found
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x0000712a26a72000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x0000712a25f17000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x0000712a25600000)
    libzstd.so.1 => /lib/x86_64-linux-gnu/libzstd.so.1 (0x0000712a25946000)
    /lib64/ld-linux-x86-64.so.2 (0x0000712a26b8d000)

It suggests that build_dpkg.sh got some missed/broken check or broken/no dependancy check. I see when bash -x ./build_dpkg.sh that ldd screams with error

Temporary workaround for this:

find / -name "libpython3*so"
/usr/lib/x86_64-linux-gnu/libpython3.12.so
/usr/lib/python3.12/config-3.12-x86_64-linux-gnu/libpython3.12.so

ln -s /usr/lib/x86_64-linux-gnu/libpython3.12.so.1.0 /usr/lib/x86_64-linux-gnu/libpython3.10.so.1.0

There's a fix for this in the new build_dpkg.sh that hasn't shipped yet.

https://github.com/LibreQoE/LibreQoS/commit/68abb2b5b422211f798bd91d8e619fca90448112 https://github.com/LibreQoE/LibreQoS/commit/dbd1b6b46dd59cefa3088374611990800e02d4ce

It's similar - it scans lqosd with ldd, and then looks for an alternative libpython to connect to.

Ohhhh i even little improve that code range. So after rebuild of deb package this issue could be closed. Probably -beta2?

Checked again that on newest state of develop branch, it's not existing anymore. So I close this. Thanks for tagging.
