Comment 1 for bug 1818129

Hi Jochen,
I just came by looking at targetcli-fb and found that bug.
Let me update a few things to the current state.

$ dpkg -L targetcli-fb | grep back
/etc/rtslib-fb-target/backup

$ dpkg -l targetcli-fb
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
+++-==============-============-============-======================================================
iU targetcli-fb 2.1.fb49-1 all Command shell for managing the Linux LIO kernel target

That is on focal, so the issue is resolved.
The issue was resolved in targetcli-fb 2.1.43-2

Therefore Bionic still is affected, but all following versions are fixed.
