[Bug 2143014] Re: unable to upgrade from 25.10 to 26.04

[Julian Andres Klode]

I do not see any error in the output or the log files.

I note openssl is reported as foreign; likely because the new version in
26.04 has not migrated yet, so 26.04 only offers an older version at
this time.

I hope this addresses your concerns.

  The following unofficial packages are currently installed:

  openssl-provider-legacy..Installed from: unknown origin

  
  It is recommended to install supported versions from the Ubuntu
  archive, and try the upgrade again.

  Do you want to continue the upgrade anyways?

  Continue [yN]
