[Hexanet]

Hi everyone,

I have try to upgrade from V18 to V20 but the error log does not really help :

/usr/sbin/3CXUpgradeDebian10: ligne 9: /tmp/update.sh: Permission non accordée

Does anyone have already seen this ? Any idea why ?
I have checked the usual point of failure but without success

Thanks !

I tried to upgrade from V18 to V20 last night and running into similar issues. It looks like maybe the repos are no longer available to download the upgrades from? Can someone from 3CX re-enable the repos please? =D

You should just backup, reinstall and restore at this point. v18 isnt supported on the forum anymore.

Thanks for your reply.
Of course it's a solution but I've try on another 3CX Vm and have the exact same error.
I think something goes wrong on the script.
I can update to 18.9B but not to V20.

So youre telling me you cannot do a fresh install of v20 and restore your backup?

 

[Hexanet]

No, I'm telling you I have the same exact error on trying to upgrade an other V18 install.

Having been updating a bunch for the last couple of days and did not encounter this issue.

 

[Hexanet]

I have too, but I like to prepare lots of upgrade and don't want to restore backups for each.

Ok, I've found what was the cause.
/tmp on these VM have a noexec option in their fstab.
Thanks for your messages everyone.
