Hi,
When a system is configured with no sources.list, or removing all
`Packages` files under /var/lib/apt/lists, running apt install with
a ReGex matching a local package and a non-existent version, apt doesn't
work as expected. For instance, running `apt installing '^apt$=10000`
is not failing.
Steps to Reproduce:
1. Remove sources.list and Removing all files under sources.list.d/
2. Run apt update to clean all caches
3. Run apt install '^apt$'=1000
Expected Behavior:
$ LANG=C apt install '^apt$'=1000
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package apt is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Version '1000' for 'apt' was not found
$ echo $?
100
Actual Behavior:
$ LANG=C apt install '^apt$'=1000
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'apt' for regex '^apt$'
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
$ echo $?
0
After bisecting the source, we found that this bug is introduced in "Allow =version
and /release selector on virtual packages" (572810e9f321237873d1536c88991d7825c6f1db).
In apt-pkg/cacheset.cc:493, when `Match.Find()` fails, the program runs
helper.canNotGetVersion(CacheSetHelper::VERSIONNUMBER, Cache, P).
However, ShowErrors are set previously in apt-pkg/cacheset.cc:468:
if (pkgset.getConstructor() != CacheSetHelper::UNKNOWN)
errors = helper.showErrors(false);
When attempting inserting error "Version '%s' for '%s' was not found" in
canNotGetVerFromVersionNumber, the error is ignored with ShowError=false;
A possible fix is to set ShowErrors to true before helper.canNotGetVersion()
and set it back afterwards.
Thanks!
Tianyu Chen @ deepin
