tr trick does not work in the initramfs environement. (initramfs) echo "81780AD9-068C-4A80-A795-56856973B8F9" | cut -f 2 -d = | tr '[ :upper:]' '[:lower:]'
81780AD9-068C-4A80-A795-56856973B8F9 But awk works: (initramfs) echo "81780ad9-068c-4a80-a795-56856973b8f9" | awk '{print tolower($0)}' 81780ad9-068c-4a80-a795-56856973b8f9 I will resubmit the patch using awk instead. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1548120 Title: [xenial][initramfs-tools] support uppercase and lowercase uuids Status in initramfs-tools package in Ubuntu: Fix Released Bug description: Initramfs tools does not support uppercase UUIDs.
