installation timed out, unable to lock database

sorin-mihai commented 7 years ago

Hello,

I've seen this quite a few times, I figured it's not a big deal since the error appears after the packages are installed. I won't paste the whole output, some of it is in Romanian, but this is the end of it; please let me know if you need the whole output.

The problem looks like caused by a running pacman at the same time, but there is none, and that lock file shouldn't exist; obviously it's not there when I check. The system is running a full gnome session, but beside that, only terminal window is really active, where the build_and_install_all.sh script is ran, everything else is idle.

Thanks for your report. I also experienced a slow relabeling process when installing large packages like kernels (linux-selinux, linux-hardened, etc.). The "Time out" message comes from the expect program in script build_and_install_all.sh, which was needed in order to install a package which conflicts with a core package.

There are therefore two issues, which I am addressing with two commits:

https://github.com/archlinuxhardened/selinux/commit/1427658177e989137cc89720b30618dd5efcc7d4 (selinux-alpm-hook 0.1-3 update) should make the SELinux relabeling hook faster,
https://github.com/archlinuxhardened/selinux/commit/18eaa603b99439bd35dd0b7676a9ebd408b23e6a (currently in branch pacman-ask) replaces the expect program with pacman's --ask=4 option. This removes the "Time out" issue.

Could you please test these two commits?

I used the master branch, all seemed fine.
