I have a lot of software on the operating system, and now Ubuntu update is delivering version 19.
How can I upgrade the operating system without removing the software and having to reinstall the software on the operating system?
It will not remove your software it will only upgrade your base system and some of the packages that are available in the repo. if any that do get removed will be old system packages and dependencies that most likely replaced by alternatives. you can back up your system. in conclusion, Ubuntu will not delete any packages and software and settings don't worry. back up is the only way
do-release-upgrade
& upgrade tools perform as Jos has stated, or you can use 'something-else' on install media (and not selecting format; but this applies to Ubuntu repo software only)/etc/apt/sources.list.d
and re-enable them. But it is rare that a package stops functioning completely after an upgrade.ukuu
andjNetMap
probably unnecessarily.jNetMap
is just a network map/pinging python app. Newer versions (19.00+) ofukuu
are now paid apps, but older versions (18.XX) could have been left alone.
