The GitHub Actions CI jobs have been updated to fix breakages caused
by the move to Ubuntu 26.04 runner images, including using 'apt-get'
instead of 'apt' for stable CLI output, elevating permissions when
replacing system binaries, and temporarily pinning the 'linux32' job
to Ubuntu 24.04 to avoid seccomp-related networking failures.
* hn/ci-ubuntu-26.04-fixes:
ci: pin linux32 to ubuntu-24.04 to restore networking
install-dependencies: work around a permission problem
ci: use apt-get in the linux32 job
