Issue with apt installer

[sprudel79]

Hi everyone,
our Dockerfile to create a customized Teamcity Docker agents starts with the following lines:

FROM jetbrains/teamcity-agent:latest
RUN apt-get update
...

Trying to build the image results in the following error:

E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/

Docker version is 19.03.09 running on Linux Mint 19.3 by the way.
Is this an issue coming from the base image?
Thanks in advance.

Hi, try inserting USER root before RUN instruction

Hope this helps,

Thanks @kir , it works now again.
But out of curiosity, was there any change in the base image that has caused this behaviour?

This happens due to this change: https://youtrack.jetbrains.com/issue/TW-65785
Glad it works again for you :)

Perfect, so it's crystal clear for me now.
Thanks again for the instant support.
