Bug #1624644 claims U-U does not work well with Software Updater a.k.a.
update-manager. Can you confirm?
You received this bug notification because you are a member of Ubuntu
Touch seeded packages, which is subscribed to unattended-upgrades in
Kernels not autoremoving, causing out of space error on LVM or
Encrypted installation or on any installation, when /boot partition
Status in unattended-upgrades package in Ubuntu:
Currently if one chooses to use LVM or encrypted install, a /boot
partition is created of 236Mb
Once kernel updates start being released this partition soon fills
until people are left unable to upgrade.
While you and I might know that we need to watch partition space, many
of the people we have installing think that a windows disk is a disk
and not a partition, education is probably the key - but in the
meantime support venues keep needing to deal with the fact the
partition is too small and/or old kernels are not purged as new ones
For workaround and sytem repair, see
