Probably just a bad download.
Normally the following will correct such issues:
sudo apt clean
sudo apt update
sudo apt install , in this case sudo apt install libitm1
Obviously not still an issue so long after reporting so will close as
'Invalid'.
** Changed in: ubuntu
Status:
Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug. I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross
