FreeBSD: pkgbase: major upgrades

A rough guide, for alpha testing on AMD64:

• tested with FreeBSD 15.0-ALPHA2 and ALPHA3
• things might be less rough with ALPHA4, with or without the next release of ports-mgmt/pkg.

Not intended to be comprehensive.

Preamble

It's conventional to upgrade the userland part of base before upgrading non-base packages.

The numbered steps below break from convention. The disorderly approach is a workaround to pkg issue #2414. Proceed with caution.

Also, please note:

• FreeBSD bug 289097 affecting /root/.cshrc and /root/.profile – fixed (cherry-pick, 2025-10-01)
• pkg solver is looking at too many packages · Issue #2520 · freebsd/pkg – this might be an underlying cause of issue 2414 above
• BACKUP_LIBRARIES improvements · Issue #2501 · freebsd/pkg
• pkg: sqlite error while executing BEGIN IMMEDIATE TRANSACTION in file pkgdb.c:1206: cannot start a transaction within a transaction · Issue #2522 · freebsd/pkg – reportedly fixed in pkg 2.4.0
• libpkg: Support system triggers · freebsd/pkg@7831a19 (2025-09-18) – version 2.3.1 of pkg does not include this base-related enhancement
• if you had a minimal installation of the OS prior to upgrade, you might want to install FreeBSD-bsdconfig, FreeBSD-csh, and FreeBSD-ee – or the meta package for their set(s) – after the upgrade
• Desktop environments: FreeBSD Project-provided packages in the ports collection
• last but not least, freebsd-update and pkgbase – discussion, an outcome of which should be a tool that frees us from the complexity below.

24. history -S

33. env ABI=FreeBSD:15:amd64 pkg-static upgrade
34. if the upgrades were successful, history -S then exit and shutdown -r now
35. ee /usr/local/etc/pkg/repos/FreeBSD.conf
36. modernise the repository names – FreeBSD-ports and FreeBSD-ports-kmods
37. pkg install -nU -r FreeBSD-base --glob 'FreeBSD-set-*'
38. decide whether you want any base meta package (for a FreeBSD Project-defined set of packages)
39. pkg install -nU -r FreeBSD-base --glob 'FreeBSD-*'
40. decide whether you want any additional base package
41. when you're certain that bootstrap will not result in a downgrade, pkg-static unlock -y pkg && pkg bootstrap -fy

Dry runs of a major upgrade from RELEASE to CURRENT, preceded by a fetch of packages:

• 0 (zero) removals with --repository FreeBSD (FreeBSD-ports)
• 906 removals with --repository FreeBSD-base
• 6 removals without specifying a repository.

A non-dry run of the third option does fetch additional packages.

The fetch-after-fetch effect was noted a few days ago:

• freebsd/pkg#2414 (comment)
• freebsd/pkg#2414 (comment)

Now, it's nice that I can avoid hundreds of unwanted removals by not specifying a repository.

Previously, with a major upgrade to 15.0-ALPHA3, it was necessary to specify the FreeBSD (ports) repository for a disorderly upgrade (port packages before userland).

Now, it's nice that I can avoid hundreds of unwanted removals by not specifying a repository.

False!

I completed a major upgrade from 14.3-RELEASE-p3 to (unannounced) 15.0-ALPHA4:

• with pkg 2.2.2 locked prior to the upgrade
• without an sqlite error 👍
• in a single step, without specifying a repo (not recommended, but I'm pleased that it worked).

Around a week later, sqlite-related issue 2522 recurred – not involving pkgbase, as far as I can tell.

The issue has been reproduced and diagnosed.
