Title: Questions about Avast 8 Linux
Post by: argonvegell on March 21, 2014, 05:47:27 PM
Is Avast 8 Linux compatible with 32-bit Linux?

Can I have the old Avast 4 Linux installed alongside Avast 8 Linux, or do I have to uninstall Avast 4 Linux.

Thanks.

Yes. The i386 platform is supported.

Can I have the old Avast 4 Linux installed alongside Avast 8 Linux, or do I have to uninstall Avast 4 Linux.

No. The new packages are marked as avast-4 package replacements, so the package manager won't let You install the new version until you remove the old one.

Thank you for the quick reply.

The VPS update problem from Avast 4 Linux, as noted here;

Starting with the 400.vps, version 100328-1, one of it's internal block reached the inner limit 33554432 bytes. It's a kernel variable which
is (quite artificially) limiting the maximum size of any SHM memory block - and 33554432 was a default for some kernels.

Solution? Set the limit to higher values (as root):

sysctl -w kernel.shmmax=128000000
OR
echo 128000000 >/proc/sys/kernel/shmmax

Place those lines to /etc/init.d/rcS or equivalent file (it's distribution-specific a bit - see /etc/inittab, the sysinit runlevel) to have them set automatically (just after boot).

regards,

Is this still an issue with Avast 8 Linux?
