Bug#990447: fwupdmgr: Unable to install new updates



Same issue here on my Lenovo ThinkPad X390 when upgrading from ECP 1.17 (N2JHT33W) to 1.23 (N2JHT39W). NB: .cab files downloaded on Lenovo website manually (no LVFS because files are too old there).

I'm on Buster with the following shim/fwupd versions:

$ dpkg -l | awk '$2 ~ /shim/ || $2 ~ /fwupd/{print}'
ii fwupd 1.2.14-1~deb10u1 amd64 Firmware update daemon ii fwupd-amd64-signed 1.2.14+1~deb10u1 amd64 Tools to manage UEFI firmware updates (signed) ii libfwupd2:amd64 1.2.14-1~deb10u1 amd64 Firmware update daemon library ii shim-helpers-amd64-signed 1+15.4+7~deb10u1 amd64 boot loader to chain-load signed boot loaders (signed by Debian) ii shim-signed:amd64 1.38~1+deb10u1+15.4-7~deb10u1 amd64 Secure Boot chain-loading bootloader (Microsoft-signed binary) ii shim-signed-common 1.38~1+deb10u1+15.4-7~deb10u1 all Secure Boot chain-loading bootloader (common helper scripts) ii shim-unsigned 15.4-7~deb10u1 amd64 boot loader to chain-load signed boot loaders under Secure Boot

Like the OP, I have no "boot order lock", I select the boot entry "Linux Firmare Update" manually and my PC then boots to my regular Linux partition with no upgrade operations...

However, unlike the OP, *it doesn't work any better after disabling Secure Boot from UEFI settings*.

Can we still say that shim is faulty (no fwupd loading)?
