When installing libnvidia-common-450 on Ubuntu-20.04 LTS, the following error occurs:
/var/lib/dpkg/tmp.ci/preinst: 6: [[: not found
This is due to preinst being a shell script ran by /bin/sh which, unlike /bin/bash, doesn’t allow the use [[ for tests.
This should be fixed. Here’s a script that actually works:
#!/bin/bash
set -e
echo "Checking for existing driver runfile install"
type -P which nvidia-uninstall 2&>/dev/null && (
echo "Removing existing driver runfile install"
nvidia-uninstall -s || :
)
exit 0
