I get the same thing. Cyanogenmod 6 RC3. Apps installing to external.

I've tried:

1) rebooting
2) deleting the market data
3) wiping cache
4) wiping dalvik cache
5) nandroid/wipe/restore
6) BART/wipe/restore
7) wipe/reflash

I've heard that installing to internal, and then moving them to external will work. I've also heard that installing one app by adb will fix it to make market work.
And finally I've heard that the following works.
Code:
rm /mnt/secure/asec/smdl2tmp1.asec

I'll be trying a few of these out, starting with the last.

*****::::::EDIT::::::*****

The above code should read:

Code:
su
rm /mnt/secure/asec/smdl2tmp1.asec

Note that in normal text, that's "rm /mnt/secure/asec/smdl2tmp1.asec". For some reason, the CODE tag makes a lower case l look like the number 1.

I should also mention that I also tried to fix permissions.

The code shown above didn't work. Terminal said that the file didn't exist.

I set it to install apps to "automatic" and that has been working since my first reply.

I had the exact same error message when trying to install the Google Maps update today and it turned out that it was because Google Maps was on the SD Card. I had moved maps to SD yesterday, then when I tried to update it, I got the error you got. I had to
1) switch the install location back to internal
2) move maps back to internal
3) clear market cache
After those 3 steps, I was able to install the update without issue. I guess some apps can not be updated if the are either on the card or maybe if they have been moved to the card.

I have the same error. None of the tips here have worked for me. It seems to be only Angry Birds that wont install...

**EDIT** Just found this -

it's smdl2tmp1.asec (with the letter L before the 2) not smd12tmp1.asec (with the number 1) :)

Oops!

Hi
Tried with exactly that text (l and not 1) but terminal says "such directory or file does not exist".
Please help...:eek:

Tried all the above hints, still not working

Hello all


Market is still not installing anything on my N1.
There is no such file in /mnt/secure/asec, and yes, got a rooted phone.
The only file there that starts with s is smpxg.jewelxmas_lite-1.asec.

Any other hints ?

I experienced this on Froyo (2.2), Froyo 2.2.1, CyanogenMod 6.0 and now also on nightly CM 6.1.

Cheers.


UPDATE: Never mind, was able to unmount
tmpfs on /mnt/sdcard/.android_secure type tmpfs (ro,relatime,size=0k,mode=000)
Then rm'd it safely. After a reboot I am back in the game.

Ok, so I'm having problems with installing Angry Birds (installation error - 18) and I have read the posts, but I honestly have no idea what to do. Someone said that this code works, but where am I suppose to type it in or alter it?

try this :rolleyes:

I got an error saying 'unknown error 18', I Google'd the error and found a possible fix, which was un-mounting the SD card. I tried, and was able to install the apps ! I then have to mount the SD card and move the apps across! It works, but its a real pain to have to keep un-mounting and mounting the sd card! :p

giv it a shot
