Meta issue for 'failed to create symbolic link '/opt/displaylink/libstdc++.so.6' (Debian)

[Barabazs]

#805
#855

Description:
Installation on Debian often fails with
ln: failed to create symbolic link '/opt/displaylink/libstdc++.so.6': No such file or directory

Potential hacky workaround:
#805 (comment)

Root cause:
this code block from 2017 which may or may not be needed anymore...

displaylink-debian/displaylink-debian.sh

Lines 425 to 430 in 512d29b

	# fix: issue #42 (dlm.service can't start)
	# note: for this to work libstdc++6 package needs to be installed from >= Stretch
	if [ "$lsb" == "Debian" ] || [ "$lsb" == "Devuan" ] || [ "$lsb" == "Kali" ];
	then
	ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /opt/displaylink/libstdc++.so.6
	fi

I don't have access to a Debian install and don't have the capacity to troubleshoot this on a VM. I would appreciate it if someone can try do comment out the code block and perform the installation on a fresh Debian install. (so not tainted with a previous displaylink install)

Hi Barabazs, I've done quickly a fresh install of debian 12. Then I've comment out the above block and could perfectly install and setup displaylink.
Also on my existing installation (Debian sid/unstable) I could install displaylink and it doesn't matter if the lines above are comment out or not.

I think these line can be removed.

Cheers

Thanks @rogue73!
Can you check if this file exists please? /usr/lib/x86_64-linux-gnu/libstdc++.so.6

@Barabazs Hi, /usr/lib/x86_64-linux-gnu/libstdc++.so.6 exist as symlink to /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30
